Cu3AsSe4
semiconductor· Cu3AsSe4
Cu₃AsSe₄ is a ternary semiconductor compound combining copper, arsenic, and selenium in a tetrahedral crystal structure, belonging to the family of chalcogenide semiconductors. This material remains primarily in research and development phases, where it is investigated for potential optoelectronic and photovoltaic applications due to its tunable bandgap and semiconducting behavior. Interest in Cu₃AsSe₄ stems from the broader family of copper-based chalcogenides, which offer promise as alternatives to conventional semiconductors in thin-film solar cells and photodetectors, though industrial deployment remains limited compared to mature technologies.
