INVESTIGATION OF ENERGETIC STATES, DETERMINED BY Cu AND Cd IMPURITY ATOMS, AT SURFACE OF GaS AND GaSe MONOCRYSTALLINE LAYERS

Abstract

The reflection, absorption, photoconductivity, and thermally stimulated luminescence (TSL) spectra of GaS:Cu and GaSe:Cu, Cd single crystals have been studied. As a result of these investigations, the energy diagram of GaS and GaSe crystals after doping was determined.
