Abstract

We demonstrate the spectral fitting analysis of action spectroscopy with a scanning tunneling microscope (STM-AS) that enables us to determine the existence of two vibrational modes that overlap in energy and also the modes which exist in lower energy region than the actually observed spectral region. These hidden properties obtained only by spectral fitting are essential for the quantitative understanding of the action spectra. The assignment of vibrational signals in the analysis follows the approximate rule of which vibrational mode is active in STM-AS that was previously proposed based on the resonant tunneling model and supporting experimental results.
