The first scanning tunneling microscope (STM) imaging and spectroscopy measurements of a single CuO2 plane at the surface of a high-Tc cuprate was reported. As such, this layer was found to be atomically ordered and to exhibit an unusual suppression of tunneling DOS at low energies. A number of possible explanations were considered and proposed that the orbital symmetry of the electronic states in the CuO2 may be influencing the tunneling process and be responsible for the observed behavior at the surface.
