摘要

80-nm high electron mobility transistors (HEMTs) with different Indium content in InxGa1-xAs channel from 52%, 70% to 100% have been fabricated. Device performances degradation were observed on the DC measurement and RF characteristics caused by impact ionization at different drain bias, >0.8V (InAs/In0.7Ga0.3As), > 1V (In 0.7Ga0.3As) and > 1.5V (In0.52Ga 0.48As), respectively. The impact ionization phenomenon should be avoided for high speed, low power application because it limits the highest drain bias of the device which in turn limits the drift velocity under specific applied electric field.
