Available in PDF, EPUB and Kindle. Book excerpt: Intensive research on semiconductor nanomaterials has increased remarkably during the past years due to their unique characteristics. Wide-band gap oxide semiconductors have occupied the forefront because of an increasing need for short wavelength photonic devices, high-power, high-frequency electronic devices. Doping with proper metal elements via introducing acceptor or donor in host material is an effective approach to tune the materials with requisite properties. Among different magnetic semiconductor materials, 3d transition metal doped ZnO has received maximum attention due to the observation of room temperature ferromagnetism with suitable magnetic dopant ions. Therefore, selection of proper doping element in ZnO has become an important route for enhancing and controlling electrical, optical and magnetic performances of nanomaterials. The objective of the present investigation is to synthesis, structural, spectroscopic and magnetic properties of transition metal ions doped ZnO nanopowders by solid state reaction with sonochemical assistance. The synthesized powders are characterized by XRD, SEM, Optical absorption, PL, FT-IR, EPR and VSM techniques.

Book Synopsis Nanopowders of Metal Oxides and Fluorides by : Sergey Yur'evich Sokovnin
Download or read book Nanopowders of Metal Oxides and Fluorides written by Sergey Yur'evich Sokovnin and published by CRC Press. This book was released on 2022-12-27 with total page 713 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the directions of nanotechnology is the production of nanopowders (NPs). Nanopowders, according to the currently widely used classification of nanomaterials, belong to zero-dimensional systems in which the limitation of wave functions occurs in all three directions. Biological methods are considered the most environmentally friendly way to synthesize NPs, but the possibility of biological contamination with mutated microorganisms cannot be ruled out. This book presents a new method for producing simple and complex metal oxide and fluoride NPs, based on the “evaporation-condensation” process using pulsed electron beam evaporation. It presents the results of more than 10 years of study of the characteristics of NPs produced using the aforementioned method. This eco-friendly method ensures the production of clean NPs, which are mesoporous and suitable for use in various applications such as medicine, spintronics, optoelectronics, dosimeters, photocatalysis, semiconductors, and ultraviolet and blue lasers. Importantly, these NPs have the potential to be used as a drug delivery system and in the creation of new nanostructures that do not contain noble metals. The book will be useful for the researchers in macromolecular science, nanotechnology, chemistry, biology, and medicine, especially those with an interest in drug delivery or cancer therapy.

Book Synopsis Transition Metals Doped Nanocrystals by : Anielle Almeida Christine Almeida Silva
Download or read book Transition Metals Doped Nanocrystals written by Anielle Almeida Christine Almeida Silva and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doping is a technique that makes it possible to incorporate substitutional ions into the crystalline structure of materials, generating exciting properties. This book chapter will comment on the transition metals (TM) doped nanocrystals (NCs) and how doping and concentration influence applications and biocompatibility. In the NCs doped with TM, there is a strong interaction of sp-d exchange between the NCs,Äô charge carriers and the unpaired electrons of the MT, generating new and exciting properties. These doped NCs can be nanopowders or be embedded in glass matrices, depending on the application of interest. Therefore, we show the group results of synthesis, characterization, and applications of iron or copper-doped ZnO nanopowders and chromium-doped Bi2S3, nickel-doped ZnTe, and manganese-doped CdTe quantum dots in the glass matrices.

Book Synopsis Transition Metal Doped ZnO for Spintronics by :
Download or read book Transition Metal Doped ZnO for Spintronics written by and published by . This book was released on 2007 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this project, the properties of transition metal (TM) -doped ZnO will be investigated. The project focuses on two activities. First, the properties of ZnO doped with transition metals (Mn, Co, or Cr) and deep level impurities (Cu, As, Sn) is explored. The primary interest will be on elucidating the origin of magnetism in the TM-doped material, including understanding the role of deep level co-dopants in mediating ferromagnetism. Experiments will focus on correlating magnetic properties (Curie temperature, moment/TM dopant) with the TM and deep level dopant concentrations. Epitaxial film growth and ion implantation of single crystals will be used in these studies. Second, for the dilute magnetic semiconducting compounds, there appears to be a correlation of Curie temperature with semiconductor bandgap. In an effort to increase the Curie temperature to greater than 300 K, the properties of TM-doped (Zn, Mg)O will also be investigated, as the addition of Mg to ZnO increases the bandgap. The epitaxial films will be grown by pulsed-laser deposition. Temperature-dependent Hall and resistivity measurements will be used to determine conduction mechanisms, carrier type, and doping. SQUID magnetometry will be used to characterize the magnetic properties of transition metal doped materials.
Book Synopsis Transition Metal Doped Zinc Oxide as Diluted Magnetic Semiconductor by : Zheng Zuo
Download or read book Transition Metal Doped Zinc Oxide as Diluted Magnetic Semiconductor written by Zheng Zuo and published by . This book was released on 2013 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal doped ZnO has been proposed to be a Diluted Magnetic Semiconductor with room temperature ferromagnetism. High quality Mn doped ZnO was grown on R-sapphire substrate. Results support intrinsic ferromagnetism, while [Mu]B/ion number was found to be larger than maximum permitted by Hund's law. Saturation strength and coercivity field was found to be manipulated by varying Mn doping concentration. Mn/Ag co-doping was found to alter saturation strength and coercivity field as well. Ag was investigated as substitution dopant to achieve high quality p-type ZnO. With optimization of growth parameters, phase segregation was suppressed and p-type was observed. Besides being p-type, Ag doped ZnO was found to exhibit room temperature ferromagnetism. This is the first high quality demonstration of Ag doped ZnO as DMS.
