Te4 Mo3 W1 Se4
semiconductor· Te4 Mo3 W1 Se4
Te4Mo3W1Se4 is a mixed-metal chalcogenide semiconductor compound combining tellurium, molybdenum, tungsten, and selenium in a layered or complex crystal structure. This is a research-phase material primarily investigated for optoelectronic and thermoelectric applications, where the combination of transition metals (Mo, W) with chalcogen elements (Te, Se) creates tunable bandgap and carrier transport properties. The material belongs to an emerging class of engineered semiconductors designed to overcome limitations of single-element or binary semiconductors in photovoltaic efficiency, thermal-to-electric energy conversion, and mid-infrared photonics.
