Cu4 P16 Se16 I4
semiconductor· Cu4 P16 Se16 I4
Cu4P16Se16I4 is a quaternary semiconductor compound combining copper, phosphorus, selenium, and iodine elements. This is a research-phase material belonging to the family of mixed-halide and chalcogenide semiconductors, primarily of interest for photovoltaic and optoelectronic applications where band gap engineering and light absorption tuning are priorities. The material's potential lies in next-generation thin-film solar cells, photodetectors, and light-emitting devices where the combination of these four elements offers tunable electronic properties unavailable in simpler binary or ternary compounds.
