· Sr2 Cu1 C1 N2 O2

Sr₂CuCNO₂ is a mixed-metal oxynitride semiconductor containing strontium, copper, carbon, and nitrogen in a complex crystal structure. This is an experimental compound primarily of research interest in materials science, belonging to the broader family of perovskite-related and layered oxynitride semiconductors being investigated for photocatalytic and optoelectronic applications. While not yet widely deployed in commercial products, materials in this composition space are notable for their potential to combine visible-light absorption with tunable band gaps, offering alternatives to traditional semiconductors for energy conversion and environmental remediation.
