It is shown that an impurity semiconductor in the presence of an external electric field can become an energy radiator with the certain frequency. Values of the frequency and external electric field, at which excited waves inside the semiconductor become instable, have been determined
Impurity semiconductor, vibrational effects, instable waves, electron and hole capture, electron and hole mobilities
