Abstract : |
Atomic resolution scanning tunneling microscope (STM) images of native and artificially created defect sites on graphite and carbon
nanotubes were compared. The presence of position-dependent coexisting superstructure patterns was identified on all of the investigated
samples. The results indicate that superstructure patterns are mainly determined by the available scattered states of the system rather
than the detailed structure of the defect site. We propose an interference model, which can explain the presence of coexisting
superstructures both on graphite and carbon nanotubes. The model predicts reduced corrugation amplitude for the case of graphite as
compared to carbon nanotubes due to the wave-vector averaging on the Fermi circle. |
