“…These applications consist of microwave field effect transistors, radio-frequency detectors, phototransistors, heterojunction bipolar transistors, quantum confinement devices and space solar cell. There are currently a vast number of reports of experimental studies of characteristic parameters such as the barrier height and ideality factor in a great variety of MS contacts [7][8][9][10]. The main characteristic parameters of MS contacts can vary as a function of the various factors.…”
