Abstract

We investigated the photoelectrical properties of the heterojunctions p-GaTe n-InSe fabricated by the method of mechanical contact of GaTe oxidized plate with van der Waals surface of InSe. The AFM-images revealed that there was formed thin oxide dielectric layer of Ga2O3 on the heterointerface p-GaTe – n-InSe. The energy band diagram was constructed. It was established that the p-GaTe n-InSe heterojunction is photosensitive in the spectral range 0,74 - 1,0 µm.
