· Cr4 Cu1 Se8 In1

Cr₄Cu₁Se₈In₁ is a quaternary chalcogenide semiconductor compound combining chromium, copper, selenium, and indium elements. This material belongs to the family of complex metal selenides and represents an emerging research compound rather than an established commercial material; such multi-element chalcogenides are investigated for potential applications in thermoelectric devices, photovoltaic cells, and other energy conversion systems where mixed-valence metal centers and layered structures can be exploited.
