Mass transport effect and surface relief formation in AsxS100-x nanolayers

Abstract

Unique structural, electronic and optical properties have determined many various applications of chalcogenide glassy (ChG) materials. The large refractive indices and third-order optical nonlinearities of the chalcogenide glasses make them the best candidates for the photonic devices to ultrafast all-optical switching and data processing.Various applications have been proposed on the basis of the light sensitivity of non-crystalline chalcogenides, especially in amorphous thin film form. Photosensitivity is a key feature of chalcogenide glasses for phasechange memory, direct waveguide and grating writing.
