Abstract

The first scanning tunneling microscope (STM) imaging and spectroscopy measurements of a single CuO₂ plane at the surface of a high-T_c 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.
