Paper Abstract

Far-infrared magnetoplasma reflection spectra of In doped Pb1-xSnxTe are measured across the band inversion region (0.15<x<0.40). From the spectra, the temperature dependeces of photo-carrier concentrations and cyclotron masses are determined below 20K, where large photoconduction is observed. By using the two bands theory with observed masses and carrier concentrations, it is found that the band edge masses become much heavior even by 1% In doping, while the band gaps do not change appreciably as compared with those of undoped Pb1-xSnxTe.
