Ca2 Bi2 Cl2 O4
semiconductor· Ca2 Bi2 Cl2 O4
Ca₂Bi₂Cl₂O₄ is an oxyhalide semiconductor compound combining calcium, bismuth, chlorine, and oxygen in a layered crystal structure. This is a research-phase material being investigated for optoelectronic and photocatalytic applications, where bismuth-based semiconductors are valued for their narrow bandgaps and potential in visible-light-responsive devices. The oxyhalide composition offers tunable electronic properties and may enable applications in solar cells, photodetectors, or environmental remediation where conventional semiconductors like Si or CdTe have limitations, though industrial deployment remains limited and material synthesis and stability require further optimization.
