A layered wide-gap oxyhalide semiconductor with an infinite ZnO2square planar sheet: Sr2ZnO2Cl2.
A new square-planar zinc oxyhalide, Sr2ZnO2Cl2, was successfully synthesized using a high-pressure method. Absorption spectroscopy revealed an indirect band gap of 3.66 eV. Electronic structure calculations indicated a strong hybridization between Zn 3dx2-y2and O 2p orbitals, which is distinct from tetrahedrally coordinated ZnO.
