Abstract :
Different types of cathode contacts are used in TEDs (transferred-electron diodes) with millimetric waves range for increase of output power and maximum generation frequency. This is, as a rule, abrupt homo- or heterojunctions. However, in graded composition III-V threefold semiconductors (variband semiconductors) the electron concentration in lateral valleys is spatially nonuniform without electron gas heating. The aim of this work is to find a system of equations for the two-level (or two-temperature model), which can be used for research of physical processes in variband diodes and to calculate the power and frequency characteristics of some variband diodes.
