CuBiSeO
semiconductor· CuBiSeO
CuBiSeO is an experimental quaternary semiconductor compound combining copper, bismuth, selenium, and oxygen elements. This material belongs to the class of mixed-valence oxide semiconductors being investigated for optoelectronic and photovoltaic applications, where the layered bismuth-chalcogenide framework offers tunable bandgaps and potential for efficient charge transport. Research interest in CuBiSeO-family compounds centers on next-generation solar cells, photodetectors, and thermoelectric devices where the combination of earth-abundant elements and structural flexibility provides advantages over conventional III-V semiconductors or lead-based perovskites.
