Abstract

In this paper, the authors present a comparison through a simulation study, among different hetero structure devices, like Metal Semiconductor Field Effect Transistor (MESFET), High Electron Mobility Transistor (HEMT), and Tunnel Field Effect Transistor (TFET), with reference to their applications in electronic field. In particular, MESFET and HEMT present good performance in power amplifiers and they are characterized by high mobility of the charge carriers that allows to consume less at high frequency. TFET is the newest experimental device, which has a very powerful application in logic circuits, ultra low-power specific analog ICs with better temperature strength and low-power SRAM.
