Abstract
Chalcogenide is the term used to reference chalcogen’s compounds with elements
such as Arsenic, Silver, Copper, Germanium, Indium, Lead etc. Its binary compound is
formed from a chalcogen anion with an electropositive element. They have wide usage in
different applications due its optical and electrical properties. Some chalcogenides observe
thermally forced crystalline amorphous phase changes used for binary encoding. This acts
as the ground work of nonvolatile memory devices. Phase change materials (PCM) is
present in amorphous phase as well as one or few crystalline phases, and they can be rapidly
and repeatedly switched between these phases. The phase change is commonly induced by
electrical heating or through optical pulses. The paper gives an overview of the electrical
properties of chalcogenides for PCM applications.
