Abstract
The photoluminescence spectrum of melt‐grown n‐CuInSe2 single crystal at 7 K, has been determined near the fundamental absorption edge. Three peaks, at approximately 0.980, 0.990, and 1.013 eV, have been observed. Considering the transition probabilities of recombination processes, donor‐to‐acceptor pair and the corresponding free‐to‐bound transitions have been identified. From the data, an absorption edge at (1.023±0.003) eV, a donor state at (10±2) meV, and an acceptor state at (33±2) meV have been determined.This publication has 23 references indexed in Scilit:
