Abstract
Micro-scale and nano-scale devices which achieve high frequency signals ug materials having increased electron saturation velocity. These devices have frequencies in the terahertz range with high temperature and radiation hard characteristics. The transit time device includes a substrate, a buffer layer and an epitaxial layer made of a material in the 43 m and 6 mm crystallographic point groups and associated alloys, and at least two contacts on the device. In operation, one contact is forward biased and the other is reversed biased. Applications for this devices include transit-time-based oscillators for use in military and civilian radar receivers, logic devices, burglar alarm and proximity alarm systems.
