Modified Positron Annihilation Model for Glassy-Like As2Se3
نویسندگان
چکیده
An approach to structural characterization of chalcogenide glasses based on the study of void distribution is discussed. The results of positron annihilation lifetime spectra measurements for glassy-like g-As2Se3 are compared with nano-void distribution data obtained from Monte Carlo simulation. In this consideration perspectives to involve the parameters of nano-voids calculated from the first sharp diffraction peak in the framework of known Elliott’s model are analyzed.

Photostructural change of glassy As2Se3 was simulated on an experimentally credible model with excited electronic dynamics within first-principles molecular dynamics. Bond breaking and bond switching reactions account for local changes around defect sites at the short time phase of illumination. For long-time relaxation, defect pairs associated with band tail states become involved in a rearran...

متن کاملAtomistic comparison between stoichiometric and nonstoichiometric glasses: The cases of As2Se3 and As4Se4
A first-principles molecular dynamics study of glassy As2Se3 and As4Se4 is presented. We focus on the differences in local structure between these glasses and identify the structural elements of As4Se4 and present a model of the material in close agreement with experiments. We analyze the vibrational modes in both models in terms of excitations of the structural elements from which each glass i...
