Abstract

This paper discusses the photosensitivity of the contact of ternary semiconductor compounds of II–IV–V₂ type with an electrolyte in natural and plane-polarized radiation. It is concluded that the high photosensitivity of the resulting contacts is determined by photoactive absorption in the II–IV–V₂ crystals. Polarization photosensitivity is detected in systems based on direct II–IV–V₂ semiconductors with a chalcopyrite lattice, and the natural photopleochroism spectra are studied. This is done by polarization photoelectric spectroscopy, making it possible to conclude that it is promising to employ the contacts of anisotropic II–IV–V₂ semiconductors with an electrolyte as polarimetric photodetectors.
