Holographic and e-Beam Image Recording in Ge5As37S58–Se Nanomultilayer Structures

摘要

Processes of e-beam and holographic recording of surface relief structures using Ge5As37S58–Se multilayer nanostructures as registering media were studied in this paper. Optical properties of Ge5As37S58, Se layers, and Ge5As37S58–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 Ge5As37S58, Se layers, and Ge5As37S58–Se multilayer nanostructures were obtained from Tauc dependencies. Using e-beam and holographic recording, diffraction gratings were fabricated in Ge5As₃₇S₅₈–Se multilayer nanostructures. Images of Ukraine and Moldova state emblems were obtained by e-beam recording. Image size consisted of 512 × 512 pixels (size of 1 pixel was ~2 μm). Ge₅As₃₇S₅₈–Se multilayer nanostructures are perspective for the direct recording of holographic diffraction gratings and other optical elements.
