SIMULATION OF GUNN DIODES WITH A STEP GRADED HOT ELECTRON INJECTOR BASED ON InGaAsP/InGaAlAs- HETEROSTRUCTURE
ABSTRAKT
Mathematical simulation of advanced Gunn diodes has been carried out with the aid of a computer Silvaco TCAD package for the purpose of developing and upgrading the devices used in radio electronics as microwave oscillators. A possibility of fabricating InP-based Gunn diodes provided with a hot electron injector made of semiconductor compounds, in particular InAlGaAs, being lattice-constant compatible with InP is investigated. A current-voltage curve with a section of negative differential resistance is obtained, as well as, transition characteristics showing the cathode current as a function of time at a given anode voltage. The conditions under which the Gunn diode generates stable high-frequency oscillations are determined.
