· Ag2Te

Silver telluride (Ag₂Te) is an intermetallic compound combining silver and tellurium, belonging to the chalcogenide materials family. It is primarily investigated for thermoelectric applications where it can convert temperature gradients into electrical current, and for specialized semiconductor and photovoltaic research due to its narrow bandgap and ionic-electronic conduction properties. While not widely commercialized in commodity applications, Ag₂Te is notable in materials research for mid-temperature thermoelectric systems and has drawn interest as a potential alternative to lead telluride-based materials in waste heat recovery applications.
