| Abstract: | Using the method of oriented crystallization of a melt (a vertical variant), we grew homogeneous single crystals of the ternary compounds CuIn3Se5 and CuGa3Se5. Photosensitive structures based on them were created for the first time, the spectral dependences of the relative quantum efficiency of the phototransformation of structures were investigated, and the energy gap width of the ternary compounds was determined. It is established that the CuIn3Se5 and CuGa3Se5 compounds are materials with direct interband transitions. We show that the structures created can be used as wide band photoconverters of natural radiation. |
