chalcogenide glass

[′kal·kə·jə‚nīd ′glas]
(materials)
A type of glass containing large amounts of one of the chalcogens tellurium, selenium, or sulfur; used in glass switches.

chalcogenide glass

A type of glass that uses chalcogen (pronounced "kal-kuh-gen") elements such as sulfur, selenium and tellurium. It has the unique property of being able to interact with both photons and electrons. Used in lenses, optical fibers, the recording layer in optical discs, it is also used in the bit cell of phase change memory. See GST, phase change disc, phase change memory and programmable metallization cell.
