On the capacitance gradient description in Heterodyne Kelvin Probe Force Microscopy
Hugo Valloire, Sylvain Clair, Christian Loppacher +2
Kelvin probe force microscopy (KPFM) probes local surface-potential variations through the electrostatic force between a conductive tip and a surface, which depends on the potentia…
Inverse heterodyne effect in bimodal Kelvin probe force microscopy
Hugo Valloire, Sylvain Clair, Christian Loppacher +2
Heterodyne Kelvin probe force microscopy (He-KPFM) enables high-sensitivity electrostatic measurements by converting a bias-modulated interaction into a resonant response at a high…
Understanding the atomic-scale contrast in Kelvin Probe Force Microscopy
Laurent Nony, Adam S. Foster, Franck Bocquet +1
A numerical analysis of the origin of the atomic-scale contrast in Kelvin probe force microscopy (KPFM) is presented. Atomistic simulations of the tip-sample interaction force fiel…
Analytical Approach to the Local Contact Potential Difference on (001) Ionic Surfaces: Implications for Kelvin Probe Force Microscopy
Franck Bocquet, Laurent Nony, Christian Loppacher +1
An analytical model of the electrostatic force between the tip of a non-contact Atomic Force Microscope (nc-AFM) and the (001) surface of an ionic crystal is reported. The model is…
Noncontact atomic force microscopy simulator with phase-locked-loop controlled frequency detection and excitation
Laurent Nony, Alexis Prof. Baratoff, Dominique Schaer +3
A simulation of an atomic force microscope operating in the constant amplitude dynamic mode is described. The implementation mimics the electronics of a real setup including a digi…
Observation of individual molecules trapped on a nanostructured insulator
Laurent Nony, Enrico Dr. Gnecco, Alexis Baratoff +7
For the first time, ordered polar molecules confined in monolayer-deep rectangular pits produced on an alkali halide surface by electron irradiation have been resolved at room temp…
