| Research Abstract |
Mixed monolayers of acetate and trifluoroacetate anions were examined by a Kelvin probe force microscope(KPFM). Obtained contact potential difference(CPD) maps showed the CPD change on the molecules. Such nanometer scale contrast in the CPD map was independent of the perturbation of cantilever oscillation frequency, cantilever oscillation amplitude, and tunneling current flowing between the tip and sample. The results proved that the nanometer scale CPD contrast by the KPFM shows true surface potential. It was found that the control of the cantilever oscillation amplitude and the investigation of tip-induced charges on the sample surface are necessary for further precise CPD analysis.
