· TeSe

Tellurium selenide (TeSe) is a binary semiconductor compound combining tellurium and selenium, belonging to the chalcogenide family of materials. It is primarily of research and developmental interest for optoelectronic and thermoelectric applications, where its layered crystal structure and tunable bandgap make it attractive for next-generation devices. TeSe is notable for potential use in infrared detectors, photovoltaic cells, and thermoelectric energy conversion systems where engineered bandgap engineering and anisotropic properties offer advantages over conventional bulk semiconductors.
