Book excerpt: While hexagonal boron nitride (hBN) in polycrystalline form has met demand for its mechanical, chemical, and thermal applications, its new electronic, optoelectronic, and nanophotonic applications required single crystals with low residual impurity concentrations. Grain boundaries and impurities need to be minimized, as they degrade the properties of hBN that are important for these new applications. The present study was undertaken to develop large area, high quality hBN single crystals at low cost, and with control over its boron isotope concentrations. Furthermore, a preliminary study was undertaken to determine if the properties of hBN could be advantageously altered by irradiation. In this study, four processes to grow and manipulate the properties of hBN single crystals were developed. First, high-quality hBN crystals were grown from an iron metal flux. The quality of crystals produced by this novel, low cost and high purity solvent was equivalent to the best reported in the literature, as verified by Raman spectroscopy, photoluminescence, defect density assessment, and current-voltage measurements. Second, hBN crystals were grown via temperature gradient method with iron-chromium flux. This method has the potential to produce larger, higher quality crystals than the slow cooling method. The maximum crystal domain size was up to 4 mm. Both in- and out-plane thermal conductivity was significantly higher than the hBN grown by slow cooling, indicating improved crystallinity. Third, monoisotopic boron hBN (h10BN and h11BN) was grown from both Fe and Fe-Cr fluxes. Raman and photoluminescence spectra show the quality of crystal grown from Fe and Fe-Cr fluxes was comparable. Fourth, neutron transmutation doping was studied as a possible method of altering the electrical and optical properties of hBN single crystals. Raman spectroscopy, photoluminescence, and electron paramagnetic resonance spectroscopies established that the effects of neutron irradiation were more pronounced on h10BN than h11BN. Together, these studies demonstrate the versatility of methods available to produce high quality hBN single crystal with specific properties.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Boron nitride is a purely synthetic material that has been known for over 150 years but only recently has sparked interest as a semiconductor material due to its potential in ultraviolet lasing and neutron detection. Thin-layer hexagonal boron nitride (hBN) is probably most attractive as a complementary material to graphene during its intense research endeavors. But for hBN to be successful in the realm of semiconductor technology, methods for growing large single crystals are critical, and its properties need to be accurately determined. In this study, hBN crystals were grown from metal solvents. The effects of soak temperature, soak time, source materials and their proportions on hBN crystal size and properties were investigated. The largest crystals of hBN measured five millimeters across and about 30 micrometers thick by precipitation from BN powder dissolved in a nickel-chromium solvent at 1700°C. High temperatures promoted outward growth of the crystal along the a-axis, whereas low temperatures promoted growth along the c-axis. Crystal growth at high temperatures also caused bulk hBN to adopt a triangular habit rather than a hexagonal one. A previously unreported method of synthesizing hBN was proven successful by substituting BN powder with elemental boron and a nitrogen ambient. XRD and Raman spectroscopy confirmed hBN from solution growth to be highly crystalline, with an 8.0 cm[superscript]-1 FWHM of the Raman peak being the narrowest reported. Photoluminescence spectra exhibited peaks mid-gap and near the band edge, suggesting impurities and defects in the hBN samples. However, high-purity reactants and post-growth annealing showed promise for synthesizing semiconductor-grade hBN. Several etchants were explored for defect-selective etching of hBN. A molten eutectic mixture of KOH/NaOH was the most effective defect-selective etchant of hBN at temperatures of 430-450°C for about one minute. The two prevalent hexagonal etch pit morphologies observed were deep, pointed-bottom pits and shallow, flat-bottom pits. TEM and SAED confirmed basal plane twists and dislocations in hBN crystals, but due to the highly anisotropic nature of hBN, their existence may be inevitable no matter the growth technique.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hexagonal boron nitride (hBN) is a wide bandgap III-V semiconductor that has seen new interest due to the development of other III-V LED devices and the advent of graphene and other 2-D materials. For device applications, high quality, low defect density materials are needed. Several applications for hBN crystals are being investigated, including as a neutron detector and interference-less infrared-absorbing material. Isotopically enriched crystals were utilized for enhanced propagation of phonon modes. These applications exploit the unique physical, electronic and nanophotonics applications for bulk hBN crystals. In this study, bulk hBN crystals were grown by the flux method using a molten Ni-Cr solvent at high temperatures (1500°C) and atmospheric pressures. The effects of growth parameters, source materials, and gas environment on the crystals size, morphology and purity were established and controlled, and the reliability of the process was greatly improved. Single-crystal domains exceeding 1mm in width and 200[mu]m in thickness were produced and transferred to handle substrates for analysis. Grain size dependence with respect to dwell temperature, cooling rate and cooling temperature were analyzed and modeled using response surface morphology. Most significantly, crystal grain width was predicted to increase linearly with dwell temperature, with single-crystal domains exceeding 2mm in at 1700°C. Isotopically enriched 10B and 11B hBN crystal were produced using a Ni-Cr-B flux method, and their properties investigated. 10B concentration was evaluated using SIMS and correlated to the shift in the Raman peak of the E[subscript 2g] mode. Crystals with enrichment of 99% 10B and>99% 11B were achieved, with corresponding Raman shift peaks at 1392.0 cm−1 and 1356.6 cm−1, respectively. Peak FWHM also decreased as isotopic enrichment approached 100%, with widths as low as 3.5 cm−1 achieved, compared to 8.0 cm−1 for natural abundance samples. Defect selective etching was performed using a molten NaOH-KOH etchant at 425°C-525°C, to quantify the quality of the crystals. Three etch pit shapes were identified and etch pit width was investigated as a function of temperature. Etch pit density and etch pit activation energy was estimated at 5×107 cm−2 and 60 kJ/mol, respectively. Screw and mixed-type dislocations were identified using diffraction-contrast TEM imaging.

This book was released on 2018-06-20 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the growth of a new type of two-dimensional (2D) material known as hexagonal boron nitride (h-BN) using chemical vapor deposition (CVD). It also presents several significant breakthroughs in the authors’ understanding of the growth mechanism and development of new growth techniques, which are now well known in the field. Of particular importance is the pioneering work showing experimental proof that 2D crystals of h-BN can indeed be hexagonal in shape. This came as a major surprise to many working in the 2D field, as it had been generally assumed that hexagonal-shaped h-BN was impossible due to energy dynamics. Beyond growth, the thesis also reports on synthesis techniques that are geared toward commercial applications. Large-area aligned growth and up to an eightfold reduction in the cost of h-BN production are demonstrated. At present, all other 2D materials generally use h-BN as their dielectric layer and for encapsulation. As such, this thesis lays the cornerstone for using CVD 2D h-BN for this purpose.

Book excerpt: Hexagonal boron nitride has been used as an inert, refractory material with excellent resistance to thermal decomposition and oxidation for more than fifty years. In the past few years, hBN has been targeted for potential electrical and optical devices such as neutron detectors, ultraviolet light emitters, deep ultraviolet light detectors, and substrates for graphene and other atomically-thin two-dimensional materials. All of these potential applications benefit from high quality, single crystals, with thicknesses varying from nanometers to microns. This research was undertaken to investigate four aspects of hBN crystal growth and recovery. (1) In an effort to optimize hBN crystal growth from a nickel-chromium flux, a series of stepped cooling experiments were undertaken. The temperature profile was stepped in a way as to promote growth in both the a and c directions, at their optimal growth conditions. Crystals were found to be typically 100-500 μm across and thickness of approximately 20-30 μm with a pyramid-like crystal habit. (2) A method for the removal of hBN crystals prior to freezing of the metal flux was demonstrated using a specialized hot pressed boron nitride crucible capable of removing hBN crystals from the flux in situ. (3) Growth of isotopically pure hBN crystals was undertaken. By modifying the crucible material for solution growth, enrichment of hBN crystals over 90% was accomplished. (4) Exfoliation of hBN has many potential applications, specifically as graphene-hBN heterostructures where layers approaching thicknesses of single atoms are most effective surface to interact with graphene as an electronic device. Several methods were tested toward exfoliating a single crystal resulting in few-layered hexagonal boron nitride nanosheets. As a result of these investigations a greater understanding of hBN bulk growth, its isotopic enrichment, its recovery, and its exfoliation was obtained.

This book was released on 2016 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hexagonal boron nitride (h-BN) is a layered material and it is similar to graphene in lattice structure. Sheets of h-BN are composed of alternating boron and nitrogen atoms in a honeycomb arrangement. The strong bond between boron and nitrogen leads to the formation of a wide bandgap (5.9eV) material. The layers are held together by weak van der Waals forces as other layered materials. Since their superb chemical stability and intrinsic insulation, h-BN can be used as a thin top dielectric layer to gate graphene and as an inert substrate for graphene transistors. So the strategy to grow high quality h-BN on a large scale is very important. My research focuses on the controllable growth of h-BN on copper substrates using the low-pressure chemical vapor deposition (LPCVD) method. In order to optimize the growth condition, I investigated how the precursor, geometric environment, substrate engineering and gas mixture affect the quality of the as-grown h-BN. Electropolishing of the Cu substrate was used to reduce the nucleation density of h-BN and hence the domain sizes increase. The evolution of varied h-BN domain shapes was explained by the underlying growth mechanism. Raman, SEM, XPS, and LEEM I-V Curve were performed on the samples for characterization. In the last part, I will show the electric properties of the device made by the as-grown h-BN.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrawide bandgap (UWBG) semiconductors, especially those in the III-nitride family of materials with their exceptional electronic, optical, and thermal properties, will play a highly important role in the next generation of ultraviolet photonic and high power electronic devices. Currently, the performance and utilization of many UWBG materials in device applications is hampered by fundamental materials challenges with growth and doping. This thesis covers the growth and materials properties of two III-nitride UWBG materials, primarily grown by molecular beam epitaxy (MBE). First, hexagonal boron nitride, a two dimensional, layered material with unique optical properties and potential applications in van der Waals-based devices and heterostructures will be discussed. Second, recent work on aluminum nitride (AlN) and aluminum gallium nitride (AlGaN) alloys will be presented.This work begins with an investigation into the high temperature MBE growth of hBN on several substrates. The layers show improved quality over previous reports and are thoroughly characterized. Next, the optical properties of these hBN films, as well as those of bulk doped hBN crystals, are investigated by cryogenic deep UV photoluminescence. Several new emission characteristics are identified and studied in these hBN materials, including carbon-induced luminescence, the direct bandgap transition of monolayer hBN, and single photon emission from hBN defects. Transitioning to the AlGaN platform, the growth of AlN and AlGaN by MBE on high quality single crystalline bulk AlN substrates is outlined and expanded upon, including an analysis of AlGaN doping with Si and Mg. The MBE growth, doping, and electron transport of heavily Si-doped, high Al mole fraction Al- GaN on bulk AlN is investigated, revealing upper practical limits to both Al mole fraction and Si doping density for high conductivity n-type films. In addition to this work on material growth and characterization, several AlGaN-based devices, an optically pumped UV laser and a Schottky barrier diode, will be introduced and discussed. These devices directly benefit from the preceding advances in AlGaN growth and doping. Finally, initial exploratory investigations and results on cubic phase BN as well as boron aluminum nitride alloys will be presented.

Book excerpt: Mono layer hexagonal boron nitride (hBN) attracts significant attention due to the potential to be used as a complementary two-dimensional dielectric in fabrication of functional 2D heterostructures. Here we investigate the growth stages of the hBN single crystals and show that hBN crystals change their shape from triangular to truncated triangular and further to hexagonal depending on copper substrate distance from the precursor. We suggest that the observed hBN crystal shape variation is affected by the ratio of boron to nitrogen active species concentrations on the copper surface inside the CVD reactor. Strong temperature dependence reveals the activation energies for the hBN nucleation process of similar to 5 eV and crystal growth of similar to 3.5 eV. We also show that the resulting h-BN film morphology is strongly affected by the heating method of borazane precursor and the buffer gas. Elucidation of these details facilitated synthesis of high quality large area monolayer hexagonal boron nitride by atmospheric pressure chemical vapor deposition on copper using borazane as a precursor.

This book was released on 2017 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The forefront of polariton research in two-dimensional (2D) materials focuses on pushing the limits of patterning 2D materials into nanoresonators and other nanophotonic structures that manipulate highly confined polaritons for technologically relevant near-IR and mid-IR applications. Furthermore, tuning the properties of hexagonal boron nitride, graphene, and other 2D materials in-plane and stacking them into heterostructures has the potential to create hybrid optical, electronic, thermal, and mechanical properties with a wealth of new functions. To fully tailor these novel properties, controlled nanoscale patterning of these and other van der Waals materials is essential. Moreover, it becomes imperative to understand how patterning and geometries modify the properties within each layer or introduce defects that affect the interfaces of layered 2D heterostructures. Herein, we demonstrate high-resolution patterning of h-BN via both helium and neon ion beams and pattern a h-BN grating with a 35 nm pitch and 20 nm feature size. We study varying degrees of nanostructuring and defects via Raman spectroscopy, photo-thermal microscopy, and scattering-type scanning near-field optical microscopy and observe complimentary information about the phonon modes and the absorption and scattering of light from such nanostructures. Specifically, we observe geometry and layer dependent photo-thermal expansion of h-BN nanostructures that are mediated by phonons. This work demonstrates a thorough understanding of directly patterned 2D materials with ion beams and demonstrates that far-field and near-field measurements are essential in understanding how the nanostructuring of 2D materials can tune their properties.
