TlCr5Se7S
semiconductor· TlCr5Se7S
TlCr5Se7S is a mixed-chalcogenide semiconductor compound containing thallium, chromium, selenium, and sulfur. This is a research-phase material belonging to the family of layered transition-metal chalcogenides, studied primarily for its potential in thermoelectric and photovoltaic applications where mixed anion compositions may enable tunable band gaps and enhanced charge carrier mobility. The material remains largely experimental; its adoption would depend on demonstrating advantages in efficiency, cost, or stability over established alternatives like Bi₂Te₃ thermoelectrics or CdTe photovoltaics.
