This book was released on 1996-11-15 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book differs from previous volumes on wide bandgap semiconductors in that the emphasis is specifically on materials aspects related to electronic properties and devices. Solid advances are reported in the growth techniques of all three materials groups. In particular, the critical importance of surfaces, interfaces, doping, defects and impurities is demonstrated. Potential device applications ranging from new high-frequency, high-power all-solid-state devices to unique cold-cathode electronic devices are presented. Whilst the results demonstrate real promise for a wide range of new solid-state devices that are not feasible with current production materials, it is also evident that substantial progress in materials research is needed to fulfill the real potential of these applications. Critical issues related to the electronic potential of all three materials are addressed. Topics include: device technologies - devices, metallizations, etching, and implantation; bulk and bulk-like crystal growth; film growth; defects and structural properties; doping and electrical properties and optical and field-emission properties.

Available in PDF, EPUB and Kindle. Book excerpt: Realization of the semiconductor laser diodes (LDs) operating in the blue wavelength region had been a 'dream' for a long time for the scientists working on widegap materials until just a few years ago. Quite remarkable progress has been made in the last few years the dream has come true. The first ZnSe-based blue/green LD was fabricated about four years ago and its officially reported life-time in CW operation exceeds 100 hours now; it is quickly approaching a practical use level. Further, GaN-based blue LDs have also been realized. In this way, the progress in these research fields is quite rapid. The work includes articles on bulk growth, epitaxy, doping and characterization, blue LDs and LEDs, and future prospects in both ZnSe-based and GaN-based areas.

Download or read book III-V Nitrides Semiconductors and Ceramics written by B. K. Meyer and published by Elsevier Science Limited. This book was released on 1998-07 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gallium Nitride and its alloys with InN and AlN, have recently emerged as important semiconductor materials with application to yellow, green, blue and ultraviolet portions of the spectrum as emitters, detectors and high temperature electronics. LEDs based on wide badgap GaN nitrides exhibit excellent longevity and brightness levels. Combined with red LEDs one can, for the first time, have full colour semiconductor displays. The 4 day symposium was presented at the combined 1997 International Conference on Applied Materials/European Materials Research Society Spring meeting (ICAM'97/E-MRS'97) held in Strasbourg (France) from 16-20 June 1997, provided a forum for active nitride researchers covering the most recent developments in all areas of nitride semiconductors. Sessions focused on the aspects of epitaxial and bulk growth of GaN and its alloys, on optical properties and structural and electrical characterisation, quantum phenomena and light-emitting devices such as LEDs and laser diodes.

This book was released on 2013 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In the past twenty years, III-nitride devices have had an enormous impact on semiconductor-based technologies. This impact is seen in both optoelectronic and electronic devices. The aim of this dissertation is to take advantage of III-nitride nanowires grown by plasma-assisted molecular beam epitaxy to form heterostructures that are difficult or impossible to achieve in traditional, thin films. To do this, it is first necessary to establish the growth phase diagrams that correlate the characteristics of GaN nanowires to MBE growth conditions. By using the information in these growth maps we can control growth kinetics and the resulting nanowire structures by making strategic, timely changes to growth conditions. Using this control electronic and optoelectronic III-nitride nanowire devices are created. First, coaxially-oriented AlN/GaN nanowire resonant tunneling diodes are formed on Si substrates. Second, polarization-induced nanowire light emitting diodes (PINLEDs) are fabricated that exhibit electroluminescence at wavelengths from the deep UV into the visible. Because these PINLEDs utilize polarization doping, they can be formed with and without the use of dopants. Device and structural characterization are provided, including a detailed investigation of the mixed material polarity in these nanowires. Finally, the dissertation closes with a discussion of recent work and future ideas for optimizing the PINLED design.

Book excerpt: "The photoelectrochemical (PEC) approach of converting solar energy into fuels holds significant potential to establish a sustainable energy system. Tremendous effort has been devoted to metal oxide based PEC systems. However, it remains elusive to reach the calibre for application in terms of efficiency, stability and scalability, due to the intrinsic limits of metal oxide light absorbers. Herein, we demonstrate the versatility of indium gallium nitride (InGaN) alloys grown by plasma-assisted molecular beam epitaxy (PA-MBE) for the purpose of water splitting under sunlight. Using tunnel junction nanowires, we realize a monolithically integrated InGaN-nanowire/Si tandem photocathode with dramatically improved efficiency and stability compared to other Si-based photocathodes. Besides, we establish a growth window to produce high quality InGaN alloy nanowires with indium content as high as 50%, which unprecedentedly extends the absorption edge to ~700 nm and leads to the highest photocurrent of InGaN photoelectrodes under AM1.5G one sun illumination. Based on such InGaN nanowires, we further construct an InGaN-nanowire/Si tandem photoanode with an energy bandgap configuration approaching the ideal values of 1.75 eV (top cell) and 1.13 eV (bottom cell) for tandem photovoltaic devices. Such an innovation brings us one step closer to unassisted PEC water splitting with a solar-to-hydrogen (STH) efficiency above 20%. We have successfully coupled the tandem photoanode with NiFeOx water oxidation co-catalyst, reaching a peak STH of 1.3% for water splitting in strong base electrolyte. In addition, we explore the photocatalytic properties of GaN nanowires for the formation and cleavage of C-H bond. Under UV illumination, photocatalytic CO2 reduction towards CO and CH4 is observed on GaN nanowires with Pt nanoparticles as co-catalyst. The difficulty of C-H bond formation on GaN nanowires inspires us to study the cleavage of C-H bond on the surface of GaN nanowires under UV illumination, which leads to the photocatalytic conversion of CH4 to benzene." --
