Lead telluride

Description:
Lead telluride (PbTe) is a binary compound composed of lead and tellurium, classified as a semiconductor material. It typically appears as a gray or black crystalline solid and exhibits a diamond cubic crystal structure. PbTe is notable for its high thermoelectric efficiency, making it valuable in applications such as thermoelectric generators and coolers. The material has a relatively high melting point and demonstrates significant electrical conductivity, particularly at elevated temperatures. Its bandgap is small, which allows it to absorb and emit infrared radiation, making it useful in infrared detectors and sensors. Lead telluride is also characterized by its ability to form solid solutions with other chalcogenides, which can be tailored for specific electronic and thermal properties. However, it is important to handle PbTe with care due to the toxicity of lead, necessitating appropriate safety measures during its use and disposal. Overall, lead telluride is a significant material in the fields of materials science and solid-state physics, particularly in the context of energy conversion technologies.
