STM Imaging of HOPG

 

 

Figure 7. Schematic illustrations of the layered structure of HOPG: side-view (a) and top-view (b).

 

 

Figure 1. STM image of HOPG (2x2 nm2, 48 Hz). The cross-section view below the image corresponds to the line drawn in the image.

 

Figure 2. STM image of HOPG (2x2 nm2, 8 Hz). The cross-section view below the image corresponds to the line drawn in the image.

Figure 4. Schematic illustration of two types of atomic arrangements that are detected by STM for HOPG surface. (a) pp orbital interactions between f A and f B, and the band orbitals (ef: Femi level). (b) 3-for-6 pattern. (c) 6-for-6 pattern.
