Research Abstract

We investigated the emergence of new phenomena at a heterologous interface between well-controlled molecular assembly and good conductor materials. A coulomb blockade transport emerged in continuous polymer layer has been found, and its model was proposed. The investigation of circularly-polarized light emission from molecules adsorbed on solid surface provided a new finding of assembled chiral structure of a few molecules. Furthermore, we successfully achieved a development of new stochastic resonance device, which functions effectively in two terminals, by using multiple pass effect and redox phenomena of single molecule at interface.
