Abstract: GaN based devices have reached a point in terms of processing maturity where the favorable wide-band gap related properties can be implemented in several commercial and military applications. However, long term reliability continues to affect large scale integration of such devices, specifically the potential of AlGaN/GaN High Electron Mobility Transistors (HEMTs), due to the indefinite nature of defects in the structure and mechanisms of performance degradation relevant to such defects. Recent efforts have begun to concentrate more on the bulk properties of the GaN buffer on which the heterostructure is grown, and how defects distributed in the buffer can affect the performance under various operating schemes. This dissertation discusses numerical simulator based investigation of the numerous possibilities by which such point defects can affect electrical behavior. For HEMTs designed for satellite communication systems, proton irradiation results indicate changes in the device parasitics resulting in degradation of RF parameters. Assumption of such radiation damage introducing fast traps indicate severe degradation far exceeding experimental observation. For power switching applications, the necessity of accurately capturing as-grown defects was realized when modeling current relaxation during bias switching. Ability to introduce multiple trap levels in the material bulk aided in achieving simulation results replicating experimental results more accurately than published previously. Impact of factors associated with such traps, either associated with discrete energy levels or band-like distribution in energy, on the nature of current relaxation characterized by its derivative has been presented.

This book presents the first comprehensive overview of the properties and fabrication methods of GaN-based power transistors, with contributions from the most active research groups in the field. It describes how gallium nitride has emerged as an excellent material for the fabrication of power transistors; thanks to the high energy gap, high breakdown field, and saturation velocity of GaN, these devices can reach breakdown voltages beyond the kV range, and very high switching frequencies, thus being suitable for application in power conversion systems. Based on GaN, switching-mode power converters with efficiency in excess of 99 % have been already demonstrated, thus clearing the way for massive adoption of GaN transistors in the power conversion market. This is expected to have important advantages at both the environmental and economic level, since power conversion losses account for 10 % of global electricity consumption. The first part of the book describes the properties and advantages of gallium nitride compared to conventional semiconductor materials. The second part of the book describes the techniques used for device fabrication, and the methods for GaN-on-Silicon mass production. Specific attention is paid to the three most advanced device structures: lateral transistors, vertical power devices, and nanowire-based HEMTs. Other relevant topics covered by the book are the strategies for normally-off operation, and the problems related to device reliability. The last chapter reviews the switching characteristics of GaN HEMTs based on a systems level approach. This book is a unique reference for people working in the materials, device and power electronics fields; it provides interdisciplinary information on material growth, device fabrication, reliability issues and circuit-level switching investigation.

While group IV or III-V based device technologies have reached their technical limitations (e.g., limited detection wavelength range or low power handling capability), wide bandgap (WBG) semiconductors which have band-gaps greater than 3 eV have gained significant attention in recent years as a key semiconductor material in high-performance optoelectronic and electronic devices. These WBG semiconductors have two definitive advantages for optoelectronic and electronic applications due to their large bandgap energy. WBG energy is suitable to absorb or emit ultraviolet (UV) light in optoelectronic devices. It also provides a higher electric breakdown field, which allows electronic devices to possess higher breakdown voltages. This Special Issue seeks research papers, short communications, and review articles that focus on novel synthesis, processing, designs, fabrication, and modeling of various WBG semiconductor power electronics and optoelectronic devices.
