DOWNLOAD EBOOKTrapping effects in III-V devices pose a great challenge to any microwave device modeler. Understanding their physical origins is of prime importance to create physics-related reliable device models. The treatment of trapping phenomena is commonly beyond the classical higher-education level of communication engineers. This book provides any basic material needed to understand trapping effects occurring primarily in GaAs and GaN power HEMT devices. As the text material covers interdisciplinary topics such as crystal defects and localized charges, trap centers and trap dynamics, deep-level transient spectroscopy, and trap centers in passivation layers, the book will be of interest to graduate students of electrical engineering, communication engineering, and physics as well as materials, device, and circuit engineers in research and industry.

DOWNLOAD EBOOKFundamentals of III-V Semiconductor MOSFETs presents the fundamentals and current status of research of compound semiconductor metal-oxide-semiconductor field-effect transistors (MOSFETs) that are envisioned as a future replacement of silicon in digital circuits. The material covered begins with a review of specific properties of III-V semiconductors and available technologies making them attractive to MOSFET technology, such as band-engineered heterostructures, effect of strain, nanoscale control during epitaxial growth. Due to the lack of thermodynamically stable native oxides on III-V's (such as SiO2 on Si), high-k oxides are the natural choice of dielectrics for III-V MOSFETs. The key challenge of the III-V MOSFET technology is a high-quality, thermodynamically stable gate dielectric that passivates the interface states, similar to SiO2 on Si. Several chapters give a detailed description of materials science and electronic behavior of various dielectrics and related interfaces, as well as physics of fabricated devices and MOSFET fabrication technologies. Topics also include recent progress and understanding of various materials systems; specific issues for electrical measurement of gate stacks and FETs with low and wide bandgap channels and high interface trap density; possible paths of integration of different semiconductor materials on Si platform.

DOWNLOAD EBOOKHigh electron mobility transistor (HEMT) is the futuristic development of the transistor in migration of the nm technology for integration of many devices in a single chip. Moving beyond the silicon-based devices to reach out the bottlenecks in the scaling and sizing of transistors has become an interesting topic of research. This research area includes the novel approach towards new materials and device structures. Materials focus is on composites made of binary, ternary and quaternary elements. Nanostructures made of two-dimensional electron gas (2DEG), quantum well and tunnel barrier make the electron transport in devices interesting. A similar approach is adopted in the present work to make the device more suitable for faster device operation with high frequency.

DOWNLOAD EBOOKThis 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.
