FIELD: physics.
SUBSTANCE: photosensitive structure can be used in designing infrared radiation detectors. The photosensitive structure has a substrate which has a variable-gap structure with a working area in which there is a working absorption layer. In the working area, besides the working absorption layer, there is a layer which prevents intrinsic defects which can adjoin the surface of the working area or at a distance from it or in the working area there is periodic structure made from alternating layers which prevent intrinsic defects and working absorption layers, with possibility of adjoining the surface of the working area or at a distance from it.
EFFECT: invention provides for maximum increase of thermal stability of parametres of photosensitive layers of the structure, which results in reduced deterioration of photoelectric and elecrophysical parametres of the photosensitive element.
