Abnormal Deviation of Temperature-Resistivity Correlation for Nanostructured Delafossite CuCrO₂Due to Local Reconfiguration

Nanostructured metal-oxide semiconductors stand at an essential frontier of nanoelectronics applications. However, their electrical properties and conductive mechanism above room temperature have not been investigated. In this study, we investigate the electrical conductivities of CuCrO2 nanoparticles using spectroscopic and computational methods. An abnormal deviation of temperature-resistivity correlation was observed, which was attributed to the local reconfiguration of nanostructures based on the bond order length strength-bond charge model. This novel perspective about electrical conduction provides valuable insights into advanced surface nanomaterial designs.
