Query: Honeycomb lattice of graphite probed by scanning tunneling microscopy
  with a carbon nanotube tip   A carbon nanotube (CNT) tip was fabricated at the apex of an etched tungsten
wire by chemical vapor deposition and used for scanning tunneling microscopy.
The honeycomb lattice of graphite in the STM images was resolved with a CNT tip
at T=79 K. The superior spatial resolution originating from the p orbitals of a
CNT is responsible for the image of the honeycomb lattice of graphite in the
STM images. The CNT tips are useful to image samples whose lattice constants
are small and to get orbital information in samples with orbital ordering due
to their superior spatial resolution with the sharp p orbitals.
