Photo-induced Mass Transfer in Chalcogenides

This work is devoted to the topical issue - photo-induced formation of surface relief gratings (SRG) in thin layers of chalcogenide vitreous semiconductors (ChVS) without following complicated chemical processing. Holographic recording technique is one of the advanced methods for direct surface relief patterning in light sensitive materials. Because of the high light and electric field gradient it is possible to obtain surface structures directly in time with illumination. This incompletely explored process which is based on the photo-induced plasticity has been discussed in this paper from the side of a light intensity and its electric field on As2S3 and other ChVS.
