Enhanced conductance response in radio frequency scanning tunnelling microscopy.

ABSTRACT: Diverse spectroscopic methods operating at radio frequency depend on a reliable calibration to compensate for the frequency dependent damping of the transmission lines. Calibration may be impeded by the existence of a sensitive interdependence of two or more experimental parameters. Here, we show by combined scanning tunnelling microscopy measurements and numerical simulations how a frequency-dependent conductance response is affected by different DC conductance behaviours of the tunnel junction. Distinct and well-defined DC-conductance behaviour is provided by our experimental model systems, which include C₆₀ molecules on Au(111), exhibiting electronic configurations distinct from the well-known dim and bright C₆₀'s reported so far. We investigate specific combinatio
