Abstract:Benzyl mercaptan-derived monolayers (X-C6H4-CH2-SH) with various substituents are interrogated on a smooth gold substrate by Electric Force Microscopy. Plots of phase shift vs. dc bias voltage are presented. The basis for the expected two-dimensional phase based image contrast is derived from these plots. The images show the EFM has sufficient contrast to function as a compositional mapping methodology for patterns of monomolecular films. The imaging mechanism is examined by utilizing simple parallel place capacitor models and compared to the resulting plots of phase shift vs. applied voltage.
