Abstract

The effect of doping by rare earth elements (REE) such as Gd, Ho and Dy at NREE ≈ 0÷10-1 at. % on initial, as well as sensibilized IR-photosensitivity in the crystals of layered semiconductor n-InSe have been investigated. It is shown that dependence of the initial and sensibilized IR-photosensitivity on the level of doping by REE in investigated InSe crystals is caused by dependence of a degree of spatial heterogeneity of a crystal, energy depth of shallow α - sticking levels and slow r-centers of recombination, and also density of shallow α - sticking levels on N REE.
