Descrizione generale

Tellurium is a p-type narrow band gap semiconducting metalloid with excellentphotoconductive and thermoconductive properties. It is widely as a fundamentalconstituent of photovoltaic solar panels, thermoelectronic devices, andalloys.

Applicazioni

Tellurium is an essential component for advanced materials including topological insulators such as thermoelectric materials and telluride nanowires. The form of this material is ideally suited for vacuum deposition techniques such as MBE.
