Available in PDF, EPUB and Kindle. Book excerpt: ZnO is a promising semiconductor material with a direct band gap energy of 3.3 eV which makes it a good candidate for UV and visible range light emitting devices. Metalorganic chemical vapour epitaxy (MOVPE) provides the possibility of industrial scale growth of ZnO, with very fine control of impurity dopants. Despite the vast recent literature on ZnO, there are very few studies of systematic intentional doping. ZnO nanowires (NWs) can be grown easily on various substrates with high crystalline quality and low defect densities and tend to exhibit reduced substrate induced strain. This enables us to perform careful spectroscopic analysis of impurity related optical transitions and identify the physical nature of various dopant species. A detailed study of low temperature photoluminescence (PL) transitions in doped ZnO NWs, thin films, and bulk crystals grown by MOVPE and chemical vapour transport (CVT) methods is presented. The standard group III donors were first investigated. Donor bound exciton (D0X) transitions previously assigned to Ga, Al, and In were confirmed in intentionally doped samples. Group IV dopants such as carbon, and tin are interesting since they can act in principle as double donors or double acceptors. We report four new shallow D0X transitions (Z-lines), at 3360.8 (Z1), 3361.2 (Z2), 3361.7 (Z3) and 3361.9 (Z4) meV, which can be greatly enhanced by co-doping with carbon tetrachloride and hydrogen. These shallow donors appear to be due to carbon impurities complexed with other unknown defects in four distinct configurations. Carbon-doped samples also exhibit two distinct acceptors with binding energies of 133 ± 5 and 181 ± 5 meV. Doping concentration and temperature dependent PL studies of unintentionally doped and Sn-doped ZnO single crystals confirmed emission from the I10 D0X transition which was recently proven to contain Sn on a Zn site. Sb-doped ZnO NWs were grown in an attempt to produce p-type material as reported by some groups. Our PL studies including Magneto PL, have shown that rather than p-doped material, the addition of small amounts of Sb-dopant resulted in a new PL transition at 3364.3 meV, which turns out to be the shallowest D0X transition so far observed in ZnO.

This book was released on 2011 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The optical properties of solar cells greatly affect their efficiencies. Decreasing the broadband and directional reflectance of solar cells increases the solar irradiance transmitted and absorbed by the cell, thereby increasing the production of electron-hole pairs. Traditional optical enhancements such as light trapping and anti-reflection coatings reduce the reflectance of silicon at an optimized wavelength and angle of incidence. They do not perform as well at high angles of incidence or over the broadband solar spectrum. Theoretical studies suggest that layers with a suitable gradient-index of refraction can create both a broadband and directional anti-reflective coating. Through their variations in height and tapered growth, Zinc oxide (ZnO) nanowires can create a gradient index anti-reflection coating. ZnO is a wide-band gap semiconductor that is non-absorbing over most of the solar spectrum. With low cost, low temperature techniques, ZnO nanowires can be grown with a variety of morphologies. ZnO nanowires were grown by aqueous chemical growth and by electrodeposition on silicon to create a gradient-index anti-reflective coating for solar cell applications. The nanowire arrays were characterized using SEM images, goniometer scattering measurements, and integrating sphere total reflectance measurements. ZnO nanowires grown by aqueous chemical growth on silicon had average diameters between 60 nm and 100 nm and average lengths between 800 nm and 1100 nm. The nanowires had vertical alignment. They exhibited relatively small diffuse reflectivities and relatively large specular reflectivities. ZnO nanowires grown by electrodeposition had greater variances in length and diameter, with average diameters between 85 nm and 180 nm and average lengths between 500 nm and 1200 nm. Electrodeposited ZnO nanowires were randomly arrayed and exhibited relatively large diffuse reflectivities and relatively small specular reflectivities. Total reflectance measurements showed that all nanowire arrays reduced the broadband reflectance of silicon. Smaller nanowire arrays outperformed the larger crystal growths. A five-fold decrease in the broadband reflectance of silicon was obtained from both vertical and randomly oriented nanowire arrays. The reflectances were constant for angles of incident below 35°. Measurements at angles of incidence greater than 35° are required to determine whether ZnO nanowires can perform as directional anti-reflective coatings and whether the morphology of the nanowires affects the directional reflectances.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials have attracted great attention in the past two decades due to their superior mechanical, thermal, chemical, electrical and optical properties entirely different from bulk materials, which lead to numerous potential applications in nanodevices and nanoelectronics, such as FETs, LEDs, single electron memory devices, spin polarized electronics, quantum computing, sensors, photonic crystals/devices, solar cells etc. Based on the previous work on Er-doped GeNWs, a core-shell nanostructure was built by introducing Zn/ZnO shell onto Er-doped GeNWs. It was found that Zn sources and corresponding surface modification processes (CVD and PVD) have important impact on Er3+ PL and ZnO UV/visible PL due to Zn2GeO4 formation, which were confirmed by HRTEM and XRD measurements. In another work, Ge and Er were used to modify the surface of ZnO tetrapods. Both strong ZnO visible PL and Er3+ PL were observed; considerable enhancement of Er3+ PL was made possible by Ge deposition as a sensitizer layer. The Zn2GeO4 phase observed could either separate from the ZnO phase or mix uniformly with the ZnO phase. As a control system, Er/GeOx/ZnO nanofibers were fabricated by electrospinning of selected sol-gel precursor solutions. These types of nanofibers exhibited strong Er3+ near IR PL at 1.54 & mum after annealing to remove the polymer template. XRD spectra indicate that the Er/Ge/Zn mixture likely forms a disordered phase, especially with high Er3+ concentrations, which contributes to the strong Er3+ PL with the reduction of Er-Er interactions. In another work, the fabrication of F-doped ZnO nanowires was investigated on different substrates with or without carrier gas (Ar). ZnO UV/visible PL spectra indicate that F-doping diminished the intensity of defect light emission at ~2.4 eV. Furthermore, ZnO/F-doped ZnO coreshell NWs were fabricated either by PVD or CVD processes; the PVD method provides better crystalline shell structures after annealing. The last work describes the fabrication of porous Ge nanowires by the anodization of Ge nanowires (grown on Si substrates) using ethanolic HCl as an electrolyte. An initial cathodic Cu electrodeposition step is found to provide useful kinetic control of the pore morphology and to stabilize the nanowires attached to the Si surface. A systematic evaluation of the role of electrolyte composition, current/voltage density, and its duration on the resultant Ge NW morphology and structure have been carried out. Preliminary photoluminescence (PL) measurements suggest strong emission in the visible region. The electrochemical anodization mechanism is discussed involving the periodic localization of pores and a varying potential distribution of free electrons along 1D GeNWs.

This book was released on 2021-04-08 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent rapid development of electronics and electro-optical devices demands affordable and reliable materials with enhanced performance. Forming nanocomposites of already well-known materials is one possible route towards novel functional materials with desirable synergistic enhanced properties. Incompatible chemical properties, mismatched crystal structures and weak bonding interactions between the substances, however, often limit the number of possible nanocomposites. Moreover, using an inexpensive, facile, large-area and flexible fabrication technique is crucial to employ the new composites in industrially viable applications. This thesis focuses on the synthesis and characterization of different zinc oxide/graphene (ZnO/GR) nanocomposites, well suited for optoelectronics and photocatalysis applications. Two different approaches of i) substrate-free random synthesis, and ii) template-assisted selective area synthesis were studied in detail. In the first approach, ZnO nanoparticles/rods were grown on GR. The obtained nanocomposites were investigated for better GR dispersity, electrical conductivity and optical properties. Besides, by adding silver iodide to the nanocomposite, an enhanced plasmonic solar-driven photocatalyst was synthesized and analyzed. In the second approach, arrays of single, vertically aligned ZnO nanorods were synthesized using a colloidal lithography-patterned sol-gel ZnO seed layer. Our demonstrated nanofabrication technique with simple, substrate independent, and large wafer-scale area compatibility improved the alignment and surface density of ZnO nanorods over large selective growth areas. Eventually, we found a novel method to further enhance the vertical alignment of the ZnO nanorods by introducing a GR buffer layer between the Si substrate and the ZnO seed layer, together with the mentioned patterning technique. The synthesized nanocomposites were analyzed using a large variety of experimental techniques including electron microscopy, photoelectron spectroscopy, x-ray diffraction, photoluminescence and cathodoluminescence spectroscopy for in-depth studies of their morphology, chemical and optical properties. Our findings show that the designed ZnO/GR nanocomposites with vertically aligned ZnO nanorods of high crystalline quality, synthesized with the developed low-cost nanofabrication technique, can lead to novel devices offering higher performance at a significantly lower fabrication cost.

Available in PDF, EPUB and Kindle. Book excerpt: Zinc oxide (ZnO) nanostructures are emerging as the key building blocks for nanoscale optoelectronic and electronic devices. ZnO has a large exciton binding energy (~ 60 meV), which makes its nanotips ideal for studying excitonic emissions in one-dimensional systems even at room temperature. ZnO nanowires show a strong exciton-polariton interaction, promising for fabricating UV nanolasers. The large and fast photoconductivity in high quality ZnO is suitable for making UV photodetectors. ZnO nanotips can be grown on various substrates, including glass, Si, and GaN, at low growth temperature (~ 400° C) by metal-organic chemical vapor deposition (MOCVD) that provides the potential of the integration of ZnO nanotips with Si based microelectronics and GaN based optoelectronics devices. To date, most of the research has been focused either on ZnO films, or on "pick-and-place" manipulation of randomly dispersed ZnO nanowires to study their physical properties. In this dissertation work in-situ n-type doping of ZnO nanotips during MOCVD is studied, including the doping effects on optical properties and electrical conductivity. Nanoscale tunneling current-voltage characteristics of the ZnO nanotips show the conductivity enhancement due to Ga doping at the proper range of doping concentration. At low or moderate doping levels, the increase in photoluminescence (PL) intensity from Ga doping is attributed to the increase of Ga donor related impurity emission. The excitonic emissions of ZnO nanotips are investigated using temperature-dependent PL spectroscopy. The sharp free exciton and donor-bound exciton peaks are observed at 4.4K, confirming high optical quality of the ZnO nanotips. Free exciton emission dominates at temperatures above 50K. The thermal dissociation of these bound excitons forms free excitons and neutral donors. Temperature-dependent free A exciton peak emission is fitted to the Varshni's equation to study the variation of energy bandgap versus temperature. A prototype of ZnO nanotips/GaN light emitting devices has been demonstrated using an n-ZnO nanotips/p-GaN heterostructure. The electroluminescence with a peak wavelength of 406nm is primarily due to radiative recombination from electron injection from n-type ZnO nanotips into p-type GaN. A novel integrated ZnO nanotips/GaN LED has been fabricated for enhanced light emission efficiency. A Ga-doped ZnO transparent conductive oxide (GZO) film and ZnO nanotips are sequentially grown on top of a GaN LED, serving as the transparent electrode and the light extraction layer, respectively. Compared with the conventional Ni/Au p-metal LED, light output power from the ZnO nanotips/GZO/GaN LED is improved by 1.7 times. The enhanced light extraction is attributed to the increased light scattering and transmission in the ZnO/GaN multilayer.

Available in PDF, EPUB and Kindle. Book excerpt: ZnO semiconductor materials, especially nanostructured materials, have potential applications in large-area electronics, photonics and optoelectronics due to their unique electrical and optical properties. ZnO nanowires have advantages of high surface area to volume ratio, with the prospective for nanoscale control of doping the electrical properties for 1-D nanoelectronic devices. Many techniques have been tried to achieve high quality ZnO nanowires in large scale with low cost and simple fabrication. However, most of these techniques require high temperatures that exclude applications in flexible electronics. P-type conductivity is another impediment for fully realizing ZnO materials for electronic device application; and this limitation has prevented advances in optoelectronic and integrated circuit applications for ZnO. To overcome the problems, this study investigated the synthesis and doping of ZnO nanowires at low temperature through a rapid electrochemical deposition growth technique. Material properties were studied using scanning electron microscopy (SEM), photoluminescence spectroscopy (PL), Raman spectroscopy, X-ray diffraction (XRD), ultraviolet to visible (UV-Vis) transmission spectroscopy, and electrical current-voltage measurements. ZnO nanowire doping was investigated using Al for n-type doping and for p-type doping, Ag/Al (co-doping) and Li. Al and Ag have significant influences on ZnO nanowire structures, while Li was found to improve the nanowire structure quality. The mechanisms for electrochemical deposition were studied through characterization of the chemical reactions, interface science and semiconductor/solution interface. It was found that the low temperature grown nanowires had high oxygen vacancy condition induced donor defect states, while, incorporation of Li dopants contributed to trap states (deep acceptor states), rather than shallow acceptor states in the band gap. Shown by XRD and PL, oxygen assisted post-growth annealing was found to promote recrystallization of ZnO and elimination of oxygen vacancies for better crystal quality and photoluminescence emission. Cr, Al or Au metals were used as contacts to Li-doped ZnO nanowires to examine electrical properties of the doped nanowires, turning out high ideal factor were obtained because of the poor contact quality due to significant surface and interface states in ZnO nanowires. At last, mechanisms of surface states related tunneling current at the metal-semiconductor interface were discussed.

This book was released on 2011 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanowires of Zinc oxide and bismuth oxide were grown on silicon substrates using vapor-liquid-solid (VLS) and unbalanced magnetron sputtering. Characterization using x-ray diffraction (XRD) and scanning electron microscopy (SEM) was conducted to investigate how growth conditions influence the structural and morphological properties of the materials. Optical properties were investigated using photoluminescence (PL), direct absorption spectra and cyclic voltammetry. The physical properties of sputtered ZnO were found to be dependent on oxygen flow rate, temperature, and the initial foreign metal catalysis seed layer. Nanowires were grown using a two-step process whereby an initial Au layer was deposited followed by Zn with oxygen. Doped ZnO-TiO 2 nanostructures were created by sputtering Ti and Zn simultaneously. Homo- and hetero-structured ZnO-ZnO and ZnO-TiO 2 were created using additional sputtering cycles. A systematic approach was taken to produce nanoarrays of Bi2 O3 by adjusting initial seed layer thickness and oxygen flow rates. A two step process involving variable oxygen flow rates was found to create the highest density of Bi 2 O3 nanowires in the array. Top-view and cross-sectional SEM micrographs suggested that the resulting Bi2 O3 nanowires were approximately 300 nm in length with diameters of 100 nm at the base and 30 nm at the top. Investigation into the growth method suggests a self-catalytic VLS-like process. Degradation tests using rhodamine 6G dye were compared to SEM images. Samples of ZnO and Bi 2 O3 displayed a direct correlation between nanowire density and photocatalytic efficiency.
