Abstract

Rare earth element effect (Mo, Dy) on the exciton spectrum of indium selenide monocrystal photoconductivity is investigated under different doping levels in a wide range of energies (1.14-1.48 eV), temperatures (77-300 K) and electric field intensity (30-240 V/cm). It is ascertained that a change of photosensitivity, shape of exciton lines, decay of excited states as well as line splitting in the stark effect are conditioned by a change of ratio between the external electric field and the field of intrinsic structural defects shielding the electron-hole interaction
