STM on HOPG shows atomic resolution In a good scanning tunneling microscopy image of highly oriented pyrolytic graphite (HOPG) you will see a pattern consisting of white, grey and black spots. To interpret the graphite STM image correctly: the bright spots mean higher tunneling current and dark spots mean lower tunneling current.

Scanning probe analysis with local atomic resolution. AFM: Atomic force microscopy: for nonconducting materials, attractive or repulsive forces STM: Scanning tunneling microscopy: for conducting materials, the tunneling current betwe It combines microwave characterization up to 6 GHz with STM or AFM an innovative technique removing the lack of temporal resolution in STM imaging. The basic idea lies on the atomic interaction between the sharp scanning tip and the atoms on the surface.

Scanning Tunneling Microscopy, or STM, is an imaging technique used to obtain ultra-high resolution images at the atomic scale, without using light or electron beams. STM was invented in 1981 by two IBM scientists named Gerd Binnig and Heinrich Rohrer. Five years later, the invention earned them the Nobel Prize in Physics.
