High number harmonic exitation by oscillators in periodic media and in periodic potential nonequilibrium electron distribution functions induced by fast ions in semiconductor plasma

Abstract

The results of experimental investigations of distribution functions of nonequilibrium electrons induced by H+ and He+ ion beams with energies 1-2,25 MeV in solid-state plasma of Ge, GaAs and CdTe semiconductors are presented. It is shown, that distribution functions have a power-law character with one power index on the whole electron energy range of 5÷100 eV being investigated; the corresponding power indices are presented. The yields of secondary electron emission induced by He⁺ ions are measured.
