Metallic Transport Behavior in a Two-Dimensional Metal Organic Framework: Copper Benzene Hexathiol (Cu-BHT)

ORAL

Abstract

Two-dimensional (2D) metal organic frameworks (MOF) have flexibilities in controlling the material properties owing to their bottom-up synthesis process and to the selectivity of metal species. We synthesized layers of 2D MOF, Copper benzene hexathiol (Cu-BHT), of thickness less than 100nm and investigated its electronic transport properties. In particular, the resistance of our highly crystalline samples decreased as the temperature was lowered, showing a metallic temperature dependence. This metallic behavior has not been observed in many organic conductors and is a prerequisite to superconductivity that can be realized in the 2D MOFs. Finally our capability of synthesizing high quality 2D MOFs paves a way to the realization of organic topological insulators [1] [2]. [1] Z.F.
