Mercury telluride ( HgTe ) is a crystalline compound from the group of Telluride, which is formed from mercury and tellurium with a ( cubic ) zinc blende crystal structure (space group). In its crystalline form, there is a direct one of the semiconductors, and II-VI compound semiconductors.

Properties

Naturally weakly p-type semiconductor material may be converted by mercury telluride doped with elements such as bromine, aluminum, gallium or indium in a n-type semiconductor when doped with zinc or copper, the p-type conductivity can be enhanced.

Mercury telluride can be prepared by the metal organic vapor phase epitaxy. Applications are in the field of solid state physics as a topological insulator.
