· K2Ti(CuS2)2

K2Ti(CuS2)2 is a ternary metal sulfide semiconductor compound containing potassium, titanium, and copper sulfide units in a layered or mixed-valence structure. This is a research-phase material being investigated for its electronic and optical properties within the broader family of transition metal chalcogenides. While industrial deployment is limited, compounds in this family show promise for photovoltaic devices, thermoelectric conversion, and catalytic applications where earth-abundant alternatives to traditional semiconductors are desired.
