Outline of Final Research Achievements

Various molecular systems which show non-linear and non-symmetric current-voltage characteristics such as rectification or negative differential resistance were studied. In the way, we found that the single molecule conductance can be expressed by the multiplicity of partial transmission probabilities of the molecular parts. With a certain kind of polyoxometalates, conductance at constant potential show dynamic signals, which can be expressed with a proposed physical model. Based on the model, we succeeded to perform reservour computing to regenerate the supervising signal.
