Surface Electronic Structure

We observed superperiodic lattices in clusters deposited on HOPG surfaces by STM. Furthermore, we clearly identified two types of bias-voltage dependences in the corrugation of superperiodic lattices. Cluster adsorption sites are strongly influenced by the superperiodic lattices. On the superperiodic lattices, clusters are found to form arrays. This suggests that one can control the surface electronic structure as well as the cluster array by preparing graphitic sheets with various stacking arrangements.

The interface between highly oriented pyrolytic graphite (HOPG) and 1-butyl-3-metyl-imidazolium hexafluorophosphate (BMIPF6) has been studied using cyclic voltammetry, electrochemical impedance spectroscopy, immersion charge measurements and in situ scanning tunneling microscopy (in situ STM).
