Our goal is to establish the molecular devices by using functional molecule. We demonstrate the electrical characteristics of single metalloporphyrin molecule by using scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS). There is zero conductance gap in current-voltage characteristics. The gap is attributed to the highest occupied molecular orbital (HOMO) – the lowest unoccupied molecular orbital (LUMO) gap and single electron charging phenomena. These results suggest that the metalloporphyrin molecule can work as a center electrode of double barrier tunneling junction at room temperature. |
