TlCr5S5Se3
semiconductor· TlCr5S5Se3
TlCr5S5Se3 is a mixed-chalcogenide semiconductor compound containing thallium, chromium, sulfur, and selenium, belonging to the family of layered transition-metal chalcogenides. This is a research-phase material that has not achieved widespread industrial adoption; it is studied primarily for its potential in optoelectronic and thermoelectric applications due to the tunable electronic structure enabled by its layered crystal architecture and mixed-anion composition. Interest in this compound stems from the broader investigation of Tl-based and Cr-based chalcogenides as alternatives to conventional semiconductors for next-generation energy conversion and light-emission devices.
