K1 Co2 Se2
semiconductor· K1 Co2 Se2
K₁Co₂Se₂ is a ternary layered semiconductor compound combining potassium, cobalt, and selenium in a defined stoichiometric ratio. This material belongs to the family of transition metal chalcogenides and is primarily investigated in research settings for its potential in electronic and optoelectronic applications. Unlike conventional binary semiconductors, the layered structure and three-element composition make it a candidate for tunable band gap engineering and novel quantum phenomena in condensed matter physics.
