Analysis and comparison of electrical characteristics for a single molecule wire with different electrode materials

In this paper, electrical characteristics of a phenyl dithiol molecule bridging between two electrodes of Pt are calculated and compared with a single molecule bridging between two electrodes of Au. The metal electrodes holding the same molecule have different transmission profiles, thereby leading to varying I-V characteristics. We use a simple model to analysis the I-V characteristic and investigate that the molecule with pt electrodes has higher current than that of with Au.
