Antimony telluride is an important thermoelectric material with potential structural advantages in the field of thermoelectricity and in the application of topo insulators.
Sb2Te3 is a semiconductor, topological insulator and thermoelectric material. These layers are stacked together through van der Waals interactions and can be stripped down into thin 2D layers. Antimony telluride belongs to group -15 metal-trisulfide. Sb2Te3 crystals have a typical transverse size of about 0.6-0.8 cm, are rectangular and have a metallic appearance.
