This was the first material used to grow epitaxial cadmium telluride and mercury cadmium telluride using metalorganic vapour phase epitaxy.^[2][3]

Dimethyl telluride as a product of microbial metabolism was first discovered in 1939.^[4] It is produced by some fungi and bacteria (Penicillium brevicaule, P. chrysogenum, and P. notatum and the bacterium Pseudomonas fluorescens).^[5]

The toxicity of DMTe is unclear. It is produced by the body when tellurium or one of its compounds are ingested. It is noticeable by the garlic smelling breath it gives those exposed, similar to the effect of DMSO. Tellurium is known to be toxic.^[6]
