· JVASP-110247· GeTe4Pb3

GeTe4Pb3 is a lead-germanium telluride ceramic compound belonging to the chalcogenide material family, characterized by its mixed-metal telluride composition. This material is primarily investigated for thermoelectric and phase-change memory applications, where its variable electrical and thermal properties enable energy conversion or rapid switching between crystalline and amorphous states. It represents an experimental composition within chalcogenide research, valued for its potential in solid-state cooling, waste heat recovery, and non-volatile memory devices where conventional semiconductors face thermal or performance limitations.
