Outline of Final Research Achievements

By using our four-tip scanning tunneling microscope prober with functionalized tips, we have measured charge and spin transport properties of various molecular objects and surfaces of electrodes which are components necessary for "molecular architechtonics" . (1) The conductivity of Nickel dithiolene nanosheets is very high and changes with redox control. (2) Bilayer graphene becomes superconducting around 2 K by Calcium intercalation. (3) The Berry phase of bilayer graphene changes from 0 to π by Li-intercalation and thermal desorption treatment. (4) A probe for pure spin injection has been developed.
