## TL;DR

This review analyzes how element substitution affects glass formation in chalcogenide semiconductor alloys.

## Contribution

The study identifies objective patterns in glass-forming ability through systematic element substitution.

## Key findings

- Glass-forming regions vary systematically with element substitution in periodic system subgroups.

- Comparative analysis reveals trends useful for designing new chalcogenide materials.

## Abstract

The creation of novel, effective materials with specific properties is necessary to advance technology. To do this, objective regularities between the material’s composition, structure, and properties must be found. A comparative analysis of glass-forming regions, arranged according to the systematic substitution of one element by its analog within a periodic system subgroup, provides a useful framework for discussing trends in glass formation in semiconductor alloys. In this review, the information on the glass formation in the chalcogenide systems GeSe2–As2Se3–MeCh, where Me = Cu, Ag, Zn, Cd, Sn, Pb; Ch = Se, Te, was subjected to a thorough comparative analysis to establish objective patterns in the change in the glass-forming ability in these systems. The effect of MeCh on the formation of glass in the binary system GeSe2–As2Se3 was traced.
