Journal of Applied Spectroscopy Aims and scope

Abstract

On the basis of the crystals of the ternary compound CuGaS2, photosensitive structures “semiconductor/natural protein” have been produced. The photoelectric properties of the obtained structures are studied in the natural and linear polarized radiation. The wide‐band character of the photosensitivity of the semiconductor/protein structures has been established in the range between the energy gap width of the semiconductor and the energy ≈3.5 eV, which is taken to serve as a pseudogap in the band spectrum of the protein. It is shown that the natural photopleochroism of the semiconductor is restorable also for its contact with protein. The possibility of the application of a new class of photosensors is discussed.
