This book was released on 1993 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Described in this thesis is an investigation of some fundamental physical properties of both zincblende and wurtzite Group III - Nitride wide bandgap semiconductor materials. All of the thin films studied were grown by plasma-enhanced molecular beam epitaxy on either GaAs and SiC substrates. This growth method proved to be suitable for nitride expitaxial growth although compromises between the plasma power and the crystal growth rate had to be sought. The zincblende polytypes of GaN and InN were studied with the intent of evaluating their potential as a wide bandgap semiconductor system for short wavelength optical devices. The metastability of these crystals has led us to the conclusion that the zincblende nitrides are not a promising candidate for these applications due to their tendency to nucleate wurtzite domains. Bulk samples of zincblende GaN and InN and wurtzite GaN, AlN and InN were studied by x-ray photoemission spectroscopy (XPS) in an effort to determine their valence band structure. We report the various energies of the valence band density of states maxima as well as the ionicity gaps of each material. Wurtzite GaN/AlN and InN/AlN heterostructures were also investigated by XPS in order to estimate the valence band discontinuities of these heterojunctions. We measured valence band discontinuities of $Delta$E$rmsbsp{v}{GaN/AlN}$ = 0.4 $pm$ 0.4 eV and $Delta$E$rmsbsp{v}{InN/AlN}$ = 1.1 $pm$ 0.4 eV. Our results indicate that both systems have heterojunction band lineups fundamentally suitable for common optical device applications.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis outlines the principles, device physics, and technological applications of electronics based on the ultra-wide bandgap semiconductor aluminum nitride. It discusses the basic principles of electrostatics and transport properties of polarization-induced two-dimensional electron and hole channels in semiconductor heterostructures based on aluminum nitride. It explains the discovery of high-density two-dimensional hole gases in undoped heterojunctions, and shows how these high conductivity n- and p-type channels are used for high performance nFETs and pFETs, along with wide bandgap RF, mm-wave, and CMOS applications. The thesis goes on to discuss how the several material advantages of aluminum nitride, such as its high thermal conductivity and piezoelectric coefficient, enable not just high performance of transistors, but also monolithic integration of passive elements such as high frequency filters, enabling a new form factor for integrated RF electronics.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of a three year program to improve the quality of Group III nitride electronic materials. The effort was directed toward understanding and controlling surface-reactive chemical paths toward the growth of GaN. We demonstrated low temperature synthesis of GaN from trimethyl gallium and ammonia by two techniques: a two-step process using atomic hydrogen and electron beams, and a single step process using only an electron beam. The electron beam activation made it possible to grow GaN in patterns. Several novel tools for the growth and processing of semiconductor materials resulted from this work. (1) A liquid N2-cooled reflector source of atomic hydrogen was developed for chemical activation and reactive cleaning of semiconductor surfaces. (2) An electron beam was used to stimulate the GaN synthesis reaction, providing a tool for activation of growth reactions which is an alternative to ion beams. These techniques were particularly effective in removing carbon associated with the methyl radical. In a parallel effort we carried out cathodoluminescence and infrared reflectance studies of GaN, AlN, superlattices, heterostructures with related wideband materials, providing information on the material defects and structure. We developed a model which allows the extraction of structural information of the component materials from infrared reflectance measurements near the restrahlen region. jg.

Book excerpt: Gallium nitride (GaN), a member of the family of III-V semiconductor compounds, has been investigated intensively and have found extensive applications. Recent development has suggested that GaN may be used as an excellent host material for light-emitting devices (LEDs) that operate in the blue and ultraviolet region, due to its wide and direct band gap. Nano-materials often present novel properties that are different from the corresponding bulk materials due to their unique structures, high specific surface area and quantum confinement effects. This book discusses several topics on the structure, thermal properties and applications of GaN. Some of these topics include the effects of radiation damage in GaN and and related materials; low-dimensional GaN; structural and dielectric properties of the GaN and silica nanoparticles investigated by molecular dynamics; and GaN bulk and nanostructures for spintronic application.

Almost everything we do, be it work, travel, communication, or entertainment, all depend on some feature of semiconductor technology. Comprehensive Semiconductor Science and Technology, Six Volume Set captures the breadth of this important field, and presents it in a single source to the large audience who study, make, and exploit semiconductors. Previous attempts at this achievement have been abbreviated, and have omitted important topics. Written and Edited by a truly international team of experts, this work delivers an objective yet cohesive global review of the semiconductor world. The work is divided into three sections. The first section is concerned with the fundamental physics of semiconductors, showing how the electronic features and the lattice dynamics change drastically when systems vary from bulk to a low-dimensional structure and further to a nanometer size. Throughout this section there is an emphasis on the full understanding of the underlying physics. The second section deals largely with the transformation of the conceptual framework of solid state physics into devices and systems which require the growth of extremely high purity, nearly defect-free bulk and epitaxial materials. The last section is devoted to exploitation of the knowledge described in the previous sections to highlight the spectrum of devices we see all around us. Provides a comprehensive global picture of the semiconductor world Each of the work's three sections presents a complete description of one aspect of the whole Written and Edited by a truly international team of experts
