Gallium Nitride Electronics covers developments in III-N semiconductor-based electronics with a focus on high-power and high-speed RF applications. Material properties of III-N semiconductors and substrates; the state-of-the-art of devices and circuits, epitaxial growth, device technology, modelling and characterization; and circuit examples are discussed. The book concludes with device reliability aspects and an overview of integration and packaging. This comprehensive monograph and tutorial is based on more than a decade of research on materials, devices, and circuits. It is of interest to graduate students of electrical engineering, communication engineering, and physics; to materials, device, and circuit engineers in research and industry; and to all scientists with a general interest in advanced electronics.
