Apparent tunneling barrier height and local work function of atomic arrays
Spatially resolved measurements of the apparent tunneling barrier height Φ(app) in scanning tunneling microscopy have been used to estimate variations of the local work function Φ of surface structures. We experimentally show that Φ(app) can fail as a measure of Φ. The discrepancies are attributed t...
