TRANSVERSE ELECTRIC-FIELD-INDUCED MAGNETOPHONON RESONANCE IN N-TYPE GERMANIUM

We investigate the influence of the intracollisional field effect in t he hot-electron regime of the transverse magnetophonon resonances in n -type germanium. Our results show that double peaks take place accordi ng to the nonvertical transition due to the intracollisional field eff ect. One of the peaks is shifted to the lower-magnetic-field side and the other is shifted to the higher-magnetic-held side as electric fiel ds are increased and as the possible phonon energy and the difference of Landau-level indices are decreased. It is also shown that the peaks depend on the magnetic-field direction giving rise to the difference in the effective mass between the initial and final states. [S0163-182 9(98)03615-7].
