Si2 Cu4 Se6
semiconductor· Si2 Cu4 Se6
Si₂Cu₄Se₆ is a quaternary semiconductor compound combining silicon, copper, and selenium in a mixed-valence structure, belonging to the family of copper chalcogenides. This material is primarily investigated in research settings for photovoltaic and thermoelectric applications, where its tunable bandgap and potential for earth-abundant, low-toxicity device fabrication make it an alternative to conventional cadmium telluride or lead halide perovskites. The copper-selenium framework provides flexibility in band structure engineering, though device-level commercialization remains limited compared to mature semiconductor technologies.
