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.

Surface Morphologies

The knowledge of chemical functionalization for area selective deposition (ASD) is crucial for designing the next generation heterogeneous catalysis. Surface functionalization by oxidation was studied on the surface of highly oriented pyrolytic graphite (HOPG). The HOPG surface was exposed to with various concentrations of two different acids (HCl and HNO3). We show that exposure of the HOPG surface to the acid solutions produce primarily the same -OH functional group and also significant differences the surface topography. Mechanisms are suggested to explain these strikingly different surface morphologies after surface oxidation. This knowledge can be used to for ASD synthesis methods for future graphene-based technologies.
