Stimulated changes in Bi(Sb)/As2S3 nanolayered structures

Investigations of a-Se/As2S3-type chalcogenide nanomultilayers (NML) were extended towards the metal-containing Bi(Sb)/As2S3 structures. It was shown that essential changes of optical parameters (transmission, refraction and reflection) and of the electrical conductivity occur due to the interdiffusion stimulated by direct heating or by the influence of the intensive laser beam unlike the chalcogenide–chalcogenide nanostructures, where the photo-induced effects may dominate. Low temperature solid-phase synthesis, phase separation can be performed this way. Stimulated structural changes in these multilayers may be used for efficient amplitude-phase modulated optical relief recording as well as for creating surface patterns with modified electrical parameters.
