Abstract

Photoluminescence (PL) studies on LPE-grown InP layers doped with selenium and having carrier concentrations from 1 × 1018 to 1 × 1020 cm-3 have been reported in this paper. Measurements at 300 and 77 K showed that the band to band recombination peak energy shifts to values as high as 1.7 eV with increasing doping, the increase being sharp beyond 4 × 1019 cm-3. These results have been explained as being the result of the Burstein shift and the band-gap shrinkage.
