Lead telluride is a semiconductor material that can be synthesized by heating lead and tellurium in an organic solution. It is a wide-bandgap semiconductor with high chemical stability. The bandgap of lead telluride is tunable by changing the ratio of PbTe to Te, but it has a relatively high thermal expansion coefficient and low transport properties. Lead telluride exhibits strong optical absorption in the visible region, which is due to its atomic structure. Lead telluride also displays excellent thermoelectric properties, which are attributed to its temperature coefficient of resistivity and electrical conductivity.
