- Title
Structural Metastability in Chalcogenide Semiconductors: The Role of Chemical Bonding.
- Authors
Kolobov, Alexander V.; Saito, Yuta; Fons, Paul; Krbal, Milos
- Abstract
Due to their electronic configuration, chalcogenides (materials that contain sulphur, selenium or tellurium) can form different bonding geometries with the creation of metastable phases. Thus, the presence of lone-pair electrons in chalcogenide glasses results in their ability to undergo reversible photostructural changes, while resonant (metavalent) bonding in phase-change alloys is responsible for fast crystal-amorphous transition with a pronounced property contrast.
