General description

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.

Application

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.

The effect of single maternal subcutaneous (s.c.) injection of 0.12 mg/kg diphenyl ditelluride, (PhTe)2, diluted in canola oil at days 6, 10 or 17 of gestation were evaluated in Wistar rats. The reduction of body weight gain was statistically significant

Despite being disparaged for their malodorous and toxic demeanour, compounds of selenium, a bio-essential element, and tellurium, offer possibilities as therapeutic agents. Herein, their potential use as drugs, for example, as anti-viral, anti-microbial, anti-inflammatory agents, etc., will be surveyed along
