| Research Abstract |
Theoretical approaches of molecular transport were developed based on the non-equilibrium green's function method using the first-principles density functional method, and applied various important organic molecular bridges forming nano-links with electrodes. By these studies, fundamental mechanism and properties of the electron transport of molecules were elucidated. Important features of inelastic electron tunneling involving the excitation of molecular vibration have been clarified and bases of inelastic tunneling spectroscopy have been established. The method treating the interaction between the electron motion and molecular vibration was developed, and with it the issues of heat generation and thermal conduction were researched. The mechanism of the transition from the coherent transport to the dissipative transport has been also clarified.
