For the first time, it was discovered that the arsenic chalcogenide based nanolayers exhibit reversible photoinduced transformations of the surface structure. On the basis of topological-cluster modeling and first-principle calculations the microscopic nature of reversible transformations of nanolayers is established and recommendations for their applications as active media of ultrafast integrated-optical circuits are developed.  Product Description popup.authors Holomb Roman M.
