Abstract
Longitudinal magnetoresistance of LPE-HgTe was investigated at 4.2K under heated electron condition by using a second derivative method. Oscillation with 3~5 peaks was observed in 2~9T under electric field of around 1V/cm. These peaks are interpreted as due to the magnetophonon resonance recombination of heated electron and hole accompanied by two TA-phonon emission. It is deduced for the first time that at low temperatures TA-phonon density of states has two peaks at 2.6meV and 3.1meV.
