Abstract
Data on a detailed experimental investigation of the electron gas cooling in compensated indium antimonide in a warming electric field are presented. The electron average energy was determined from the hot electron thermoelectromotive force arising on opposite ends of the graded n-n + junction placed in a microwave electric field. It is found, that at liquid nitrogen temperature, in the samples with electron density n < 2·10 12 cm −3, the average energy of an electron decreases in comparison with the equilibrium value in a certain range of electric fields. The dependences of the longitudinal and transverse diffusion coefficients on the amplitude of microwave electric field were deduced from the hot electron thermoelectromotive force.
