Optical and Electron-Beam Recording of Surface Relief’s Using Ge<sub>5</sub>As<sub>37</sub>S<sub>58</sub>–Se Nanomultilayers as Registering Media

Abstract

Processes of e-beam and holographic recording of surface-relief structures using Ge 5 As 37 S 58 –Se multilayer nanostructures as registering media were studied in this paper. Optical properties of Ge 5 As 37 S 58 , Se layers and Ge 5 As 37 S 58 –Se multilayer nanostructures were investigated. Spectral dependencies of refractive index were analyzed within the frames of single-oscillator model. Values of optical band gaps for Ge 5 As 37 S 58 , Se layers and Ge 5 As 37 S 58 –Se multilayer nanostructures were obtained from Tauc dependencies. Holographic recording process depends on the polarization of the recording beams. Using e-beam and holographic recording diffraction gratings and other elements were recorded in Ge 5 As 37 S 58 –Se multilayer nanostructures.
