Abstract
AbstractHigh Electron Mobility Transistor (HEMT) attained great interest because of its superior electron transport making it suitable for applications in high-speed circuits and high power requirements. These devices are finding special interest to replace conventional field-effect transistors having outstanding performance in the domain of high-frequency applications. In HEMT, the high mobility of electrons and highly confined characteristics of the two-dimensional electron gas made sure that modulation doping could be utilized to have high-speed field-effect transistors having brilliant “Short Channel Effects” (SCEs) and excessive scope of scaling. However, lack of existing experimental results of such a device, designers require a dependable tool for simulation and analysis of the device characteristics in less time and low cost before device is fabricated for commercial use. Therefore, physics-based device simulator for design and performance prediction of the semiconductor device are very important. This book chapter describes an overview of the HEMT device and its physics-based simulation for performance analysis.KeywordsHEMTHeterojunction2DEGGaNInGaAs/InPTCAD simulation
