Abstract

The effect of doping by rare earth elements (REE) such as Gd, Ho and Dy at N_REE≈0≈10^-1 at. % on initial, as well as sensibiized 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 densitity of shallow α-sticking levels on N_REE.
