||A recently developed computer code is used to
investigate effects which may arise during the
STM investigation of supported nanostructures,
like carbon nanotubes. The effects of tip
geometry and point contact imaging are studied.
The calculations show that while the magnitude
of the tunnel current is determined by the
tip-nanotube tunnel gap, the asymmetry of
the tip -/+ current is influenced by the
nanotube-support tunnel gap.
The results obtained from simulation are
compared with experimental data.
