Abstract

We have used a scanning tunneling microscope to demonstrate that a single [Formula presented] plane can form a stable and atomically ordered layer at the surface of [Formula presented]. In contrast to previous studies on high-[Formula presented] surfaces, the [Formula presented]-terminated surface exhibits a strongly suppressed tunneling conductance at low voltages. We consider a number of different explanations for this phenomena and propose that it may be caused by how the orbital symmetry of the [Formula presented] plane’s electronic states affects the tunneling process.
