GeTe2

GeTe2 is a telluride-based semiconductor compound belonging to the IV-VI family of materials, combining germanium and tellurium in a 1:2 stoichiometry. This material is primarily investigated in research contexts for phase-change memory applications, infrared optics, and thermoelectric devices, where its ability to switch between amorphous and crystalline states or its narrow bandgap makes it attractive compared to conventional Si or GaAs semiconductors. GeTe2 remains largely experimental; it is valued in the materials science community for its potential in next-generation non-volatile memory and thermal management systems, though industrial adoption is limited compared to more mature germanium telluride variants like GeTe.
