Microwave oscillation of GaAs/AlAs heterostructure interval transferred electron devices

The Heterostructure Intervalley Transferred Electron (HITE) devices with a GaAs/AlAs band mixing quantum well are introduced in this paper. We briefly describe the constrictor of this new millimeter wave oscillating diode and its main oscillating behaviour. It can produce up to 320 mW at 8 mm wave band with the highest conversion efficiency of 8% and 2 W pulse output with efficiency of 10%. The function of oscillating frequency and output power versus bias voltage is investigated. At last we briefly describe the theoretical electric field and current distribution and the microwave operation model for forward and reverse-biased devices, from which the oscillating behaviour has been explained. The HITE effect and its devices have been thoroughly analyzed through this work.
