· Tl1 Se1

Thallium selenide (Tl₁Se₁) is a binary semiconductor compound belonging to the thallium chalcogenide family, typically studied as a narrow-bandgap material with potential thermoelectric and optoelectronic properties. This material is primarily of research interest rather than established industrial production, investigated for applications requiring mid-infrared sensitivity and thermoelectric energy conversion where its low lattice thermal conductivity could offer advantages over conventional semiconductors. Engineers encounter this compound in specialized contexts such as infrared detector development and advanced energy harvesting systems, where its unique electronic structure presents both opportunities and challenges compared to more mature semiconductor technologies.
