Addresses a Growing Need for High-Power and High-Frequency Transistors Gallium Nitride (GaN): Physics, Devices, and Technology offers a balanced perspective on the state of the art in gallium nitride technology. A semiconductor commonly used in bright light-emitting diodes, GaN can serve as a great alternative to existing devices used in microelectronics. It has a wide band gap and high electron mobility that gives it special properties for applications in optoelectronic, high-power, and high-frequency devices, and because of its high off-state breakdown strength combined with excellent on-state channel conductivity, GaN is an ideal candidate for switching power transistors. Explores Recent Progress in High-Frequency GaN Technology Written by a panel of academic and industry experts from around the globe, this book reviews the advantages of GaN-based material systems suitable for high-frequency, high-power applications. It provides an overview of the semiconductor environment, outlines the fundamental device physics of GaN, and describes GaN materials and device structures that are needed for the next stage of microelectronics and optoelectronics. The book details the development of radio frequency (RF) semiconductor devices and circuits, considers the current challenges that the industry now faces, and examines future trends. In addition, the authors: Propose a design in which multiple LED stacks can be connected in a series using interband tunnel junction (TJ) interconnects Examine GaN technology while in its early stages of high-volume deployment in commercial and military products Consider the potential use of both sunlight and hydrogen as promising and prominent energy sources for this technology Introduce two unique methods, PEC oxidation and vapor cooling condensation methods, for the deposition of high-quality oxide layers A single-source reference for students and professionals, Gallium Nitride (GaN): Physics, Devices, and Technology provides an overall assessment of the semiconductor environment, discusses the potential use of GaN-based technology for RF semiconductor devices, and highlights the current and emerging applications of GaN.

GaN Power Devices and Applications, provides an update on gallium nitride (GaN) technology and applications by leading experts. It includes detailed descriptions of the latest examples of GaN's usage in power supplies, lidar systems, motor drives, and space applications.

This book discusses the important technological aspects of the growth of GaN single crystals by HVPE, MOCVD, ammonothermal and flux methods for the purpose of free-standing GaN wafer production.

The book "Nitride Semiconductor Technology" provides an overview of nitride semiconductors and their uses in optoelectronics and power electronics devices. It explains the physical properties of those materials as well as their growth methods. Their applications in high electron mobility transistors, vertical power devices, LEDs, laser diodes, and vertical-cavity surface-emitting lasers are discussed in detail. The book further examines reliability issues in these materials and puts forward perspectives of integrating them with 2D materials for novel high-frequency and high-power devices. In summary, it covers nitride semiconductor technology from materials to devices and provides the basis for further research.

Franciscan University of Steubenville Professor Eugene Gan authors this first-of-its-kind Catholic roadmap for the digital age: Infinite Bandwidth: Encountering Christ in the Media. He navigates you faithfully through the digital world, encouraging frustrated parents not to throw out cell phones, ban the Internet, chuck computers, or pitch portable media devices. That would be a mistake and believe it or not would be going against more than seven decades of Catholic teaching. From Church documents on social communications, Gan extracts seven principles or "media keys" of how to approach and use media. The Church and Gan say that we must enter into the modern day "Areopagus," the social and intellectual hub of ancient Athens where Paul preached to pagans, and use the media tools God has given us to make truth known and serve mankind. Cardinal John Patrick Foley says, "Frankly, I wish that such a book had existed when I was president of the Pontifical Council for Social Communications as a text which I could have recommended. The important thing, however, is that it exists now to provide a text, context, and challenge for those who wish to bring both Christian principles and professional excellence to their work in the media." Gan offers chapter after chapter of real-life experience of how to assess movies, games, and gadgets for you and your teens. Of how to judge the merits of a film like Saving Private Ryan, and what sets it apart from Nightmare on Elm Street. Can the one be acceptable viewing and the other not? Definitely. And Gan details why. Infinite Bandwidth: Encountering Christ in the Media is way out front of the newest gizmo and will stay there thanks to its timeless principles that can be applied in all digital terrain, now and the future. Parents, educators, and students will put this book down with an entirely different attitude about the relationship between faith and media use.
