- The response of electron and phonon ensemble to the switching on and off electric field E in n-type ZnTe crystals is simulated by Monte Carlo method. The results at T=10 K show significant accumulation of LO-phonons and the LO phonon band population inversion with respect to the LA band;the inversion is necessary for the stimulated transfer of LO-LA energy difference to photons. The maximum inversion is at E=7 kV/cm. At T=300 K no phonon band inversion but fast (sub-picosecond) drift velocity switching with ≈100 GHz repetition is feasible.
