Outline of Final Research Achievements |
We have investigated the charge transport mechanisms of metal/organic monolayer/metal structures based on the observation of energy level alignment. The followings have been found; (i)contribution of the localized electronic state at the interface originating from the metal/molecule bonding, (ii)contribution of asymmetry factor of the molecular junction, (iii)contribution of different states depending on the polarity of the applied voltage. These contributions have not been considered sufficiently. Our results provide deeper understandings of the charge transport mechanisms of the molecular junctions.
