SnTe, or tin telluride, is a compound made of tin (Sn) and tellurium (Te). It is a semiconductor material known for its unique properties, including a high thermoelectric efficiency, which makes it useful in converting heat into electricity. SnTe is often studied for applications in thermoelectric devices, which can be used for power generation and refrigeration. In addition to its thermoelectric applications, SnTe has garnered interest in the field of materials science for its potential use in topological insulators. These materials can conduct electricity on their surfaces while remaining insulating in their bulk, leading to advancements in electronics and quantum computing.
