The features of the current passage phenomena under various modes, as well as photoconductivity and injection electroluminescence under various external and intracrystalline conditions in pure (in particular, undoped) and erbium (Er) doped (N≈10−5÷10−1 at.%) single crystals of layered p-GaSe semiconductor are experimentally investigated. On the basis of statistical and comparative analysis, a scientific explanation of the obtained experimental results is proposed and the possibility of creating a multifunctional optoelectronic element based on crystals of this semiconductor is shown, which combines the functions of a triac, light-controlled parameters, electroluminescent glow and current switches with an Sshaped current-voltage characteristic.
