§16§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.§ § §04§Introduction to Gallium Nitride Properties and Applications§GaN-Based Materials: Substrates, Growth Methods and Quantum Well Properties§State of the Art of GaN-Based HEMTs for Mm-Wave Applications§Technologies for Normally-Off GaN HEMTs §Status and Perspectives of Vertical GaN Power Devices§Gallium Nitride Light Emitting Diodes§Nitride-Based Laser Diodes§Blue and Green Vertical-Cavity Surface-Emitting Lasers §Reliability Issues in GaN HEMTs and LEDs§Integration of GaN with 2D Materials for Novel High Frequency Devices§ §02§Fabrizio Roccaforte is Senior Researcher at Italian National Research Council's (CNR) Institute of Microelectronics and Microsystems (IMM) in Catania, Italy.
