| Outline of Final Research Achievements |
We aimed electronic and structural controll of the organic semiconductors using Moire potential distribution of graphene surface on metal substrate. Special stress was put on the alkali-metal doping of molecular layers on graphene. In the limited period of this study, we achieved two main subjects; (1) detailed characterization of the Moire potential distribution of graphene and (2) structural and electronic characterization of the alkali-doped organic films.
(1) Using surface sensitive He atom scattering, we quantify the force constant of the graphene-substrate bonding interms of the Debye temperature and clarify the in-plane distribution of the force constant which is quite relevant in the formation of the Moire-potetial distribution.
(2) The structural detail of the K-doped monolayer of picene and coronene were studied in the molecular scale using STM. We clarify the presence of the alkali-induced reordering of the organic layer, which is in close relation to the electronic structre.
