This book was released on 2012-03 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor thin films and their junctions such as metal-semiconductor (Schottky barrier) and heterojunctions have received much attention due to their applications in various electronic and optoelectronic devices including solar cells. This book is based on the electrical and optical studies of thin film Schottky barriers and heterojunctions with an aim to use in optoelectronic devices. In this work, two wide band gap semiconductors, one Zinc Selenide (ZnSe) from group II-VI, and another transparent conducting oxide, Indium Tin Oxide are investigated in the forms of thin films and their junctions, for the possible uses as photovoltaic converter. The structural, morphological, optical and electrical (in dark and under illumination) properties of ZnSe and ITO thin films prepared at different growth conditions by thermal evaporation method have been studied by applying different experimental techniques. Schottky barriers and heterojunctions of ZnSe with different barrier metals and semiconductors have been fabricated and their current-voltage and photovoltaic characteristics are studied. The findings of it presented in this book will be helpful for the researchers of this field.

Download or read book Transparent Electronics written by Antonio Facchetti and published by John Wiley & Sons. This book was released on 2010-03-25 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenge for producing “invisible” electronic circuitry and opto-electronic devices is that the transistor materials must be transparent to visible light yet have good carrier mobilities. This requires a special class of materials having “contra-indicated properties” because from the band structure point of view, the combination of transparency and conductivity is contradictory. Structured to strike a balance between introductory and advanced topics, this monograph juxtaposes fundamental science and technology / application issues, and essential materials characteristics versus device architecture and practical applications. The first section is devoted to fundamental materials compositions and their properties, including transparent conducting oxides, transparent oxide semiconductors, p-type wide-band-gap semiconductors, and single-wall carbon nanotubes. The second section deals with transparent electronic devices including thin-film transistors, photovoltaic cells, integrated electronic circuits, displays, sensors, solar cells, and electro-optic devices. Describing scientific fundamentals and recent breakthroughs such as the first “invisible” transistor, Transparent Electronics: From Synthesis to Applications brings together world renowned experts from both academia, national laboratories, and industry.

Available in PDF, EPUB and Kindle. Book excerpt: Transparent conducting materials are key elements in a wide variety of current technologies including flat panel displays, photovoltaics, organic, low-e windows and electrochromics. The needs for new and improved materials is pressing, because the existing materials do not have the performance levels to meet the ever- increasing demand, and because some of the current materials used may not be viable in the future. In addition, the field of transparent conductors has gone through dramatic changes in the last 5-7 years with new materials being identified, new applications and new people in the field. “Handbook of Transparent Conductors” presents transparent conductors in a historical perspective, provides current applications as well as insights into the future of the devices. It is a comprehensive reference, and represents the most current resource on the subject.

Download or read book Investigation of Europium Doped Wide Band Gap Oxides and an Annealing Study of the Amorphous Oxide Semiconductor Indium Gallium Zinc Oxide written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The electronic, optical and luminescent properties of europium doped wide band gap oxide thin films and the electronic properties of indium gallium zinc oxide (IGZO), a novel amorphous oxide semiconductor were investigated. The thin films of europium doped gallium and gadolinium oxides and indium gallium zinc oxide were deposited on c-axis oriented sapphire substrates by Pulsed Laser Deposition at various conditions of temperature, pressure and doping concentration. Europium doped gallium oxide was found to be in beta phase with monoclinic crystal structure and the films exhibited intense red emission under cathode ray excitation with a peak wavelength of emission at 611 nm which corresponds to the transitions from 5D0 to 7F2 levels in europium. Europium doped gadolinium oxide thin films were found to exhibit two different phases (cubic and monoclinic) with the one of the phases being dominant depending on the growth conditions. The peak wavelength of emission was either 611 nm or 613 nm depending on the phase of the films. The amorphous indium gallium zinc oxide thin films were found to exhibit very high hall mobilities of the order of ̃15 cm2∙V−1∙s−1 and the conductivity could be controlled over several orders of magnitude from 5 x 10−3 S∙cm−1 to 10 S∙cm−1 in the amorphous phase. Annealing the films in presence of air was found to decrease the carrier concentration of the films due the incorporation of oxygen in the films thereby filling up the oxygen vacancies. Applications of amorphous indium gallium zinc oxide include Transparent Thin Film Transistors and use as transparent conducting oxide for optoelectronic devices.

Download or read book Study of Charge Transport Through Zinc Oxide Nanowire Networks for Transparent Electrodes written by Sujay Abhay Phadke and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Indium Tin Oxide (ITO) is a transparent conductor widely used for fabricating transparent electrodes in solar cells, OLEDs, flat screen displays, touch screens and electro-chromic windows. In recent years the demand for these electronic devices has shown a double digit growth. Since Indium is a rare element, the rising demand for transparent electrodes will drive up the cost of ITO multi-fold. Thus it is the need of the time to find a suitable alternative low cost transparent conductor that can replace ITO in transparent conducting electrodes. ZnO is a wide band gap semiconducting oxide (Eg ~ 3.4eV) that has the potential to replace ITO as a cheap and flexible transparent electrode material. ZnO nanowires (NWs) can be easily synthesized and n-doped using a solution based synthesis process. The solution processed ZnO NW thin films however have a high sheet resistance (~1k[ohm]/[cube] post annealing) that needs to be reduced further. Hence charge transport in ZnO NW thin films has been studied using various experimental and simulation based techniques to reveal the factors causing high sheet resistance. The effect of ZnO NW orientation on thin film sheet resistance has been studied by aligning ZnO NWs in-plane on substrates. 2D NW network simulations coupled with aligned ZnO NW thin film electrical measurements have revealed that the NW-NW junction resistance is the dominating factor affecting charge transport. Electrochemical impedance spectroscopy (EIS) characterization has experimentally confirmed the presence of high NW junction resistance and revealed that annealing affects NW junctions. TEM characterization of in-situ annealed NW junction and micro-Raman spectroscopy of annealed ZnO NW mat film have uncovered a fascinating picture of the effect of annealing on ZnO NW junctions. Furthermore a versatile E2D methodology has been developed by combining the EIS measurement technique with 2D NW network simulations for extracting individual NW junction resistance i.e. extracting nano-scale electrical properties from macro-scale EIS measurements. NW junction resistance predicted by E2D has been verified by fabricating and measuring individual ZnO NW junction and single ZnO NW devices. The E2D methodology has been shown to be promising to study charge transport in other 1D nano-structured transparent conducting ensembles. Various applications of ZnO NW thin film electrodes have been discussed and research work on further reducing the ZnO NW thin film sheet resistance has been presented.
