Photosensitive structures on single crystals of MnIn2S4: Preparation and properties

Uniform single crystals of a ternary compound MnIn2S4 have been grown by the method of directional crystallization of an almost stoichiometric melt. The problem of the creation of photosensitive structures has been solved and the first studies of the spectra of photosensitivity have been performed, which made it possible to draw a conclusion on the nature of interband optical transitions in this semiconductor and to estimate the width of the energy gap for the direct and indirect transitions. The possibility of the application of the new structures in wideband photoconverters of optical radiation is noted.
