Application

Diethyltelluride serves as a key precursor in the synthesis of cadmium telluride (CdTe) and mercury cadmium telluride (MCT) semiconductor materials used in infrared detectors and photovoltaic devices. It finds particular utility in metalorganic vapor phase epitaxy (MOVPE) for growing II-VI compound semiconductors with precise stoichiometric control. Researchers also employ this compound in nanoparticle synthesis and as a tellurium source in organometallic chemistry reactions.
