摘要: Abstract Scanning tunneling microscope pictures of graphite ordinarily show only half the atoms, B-site in closepacked hexagonal symmetry. The do not expected honeycomb structure with A- and atoms. We have obtained STM showing along well resolved atoms electronic bridge using tungsten graphite-coated probes. Repeated scanning, however, changed geometry pictures, eventually giving
