Comment on "electrostatic force microscopy on oriented graphite surfaces: coexistence of insulating and conducting behaviors".
In a recent Letter [1], Lu et al. claimed to have identified insulating and conductive regions on a highly oriented pyrolytic graphite (HOPG) surface by differences in the surface potential. Because of the reasons given below, the results presented do not give sufficient evidence to support the claims made. (1) The minimum of the force gradient signal corresponds to the contact potential differ...
متن کاملNanoscale electric polarizability of ultrathin biolayers on insulating substrates by electrostatic force microscopy.
We measured and quantified the local electric polarization properties of ultrathin (∼5 nm) biolayers on mm-thick mica substrates. We achieved it by scanning a sharp conductive tip (<10 nm radius) of an electrostatic force microscope over the biolayers and quantifying sub-picoNewton electric polarization forces with a sharp-tip model implemented using finite-element numerical calculations. We ob...
متن کاملDielectric properties of thin insulating layers measured by Electrostatic Force Microscopy
In order to measure the dielectric permittivity of thin insulting layers, we developed a method based on electrostatic force microscopy (EFM) experiments coupled with numerical simulations. This method allows to characterize the dielectric properties of materials without any restrictions of film thickness, tip radius and tip-sample distance. The EFM experiments consist in the detection of the e...
متن کاملElectrostatic-free piezoresponse force microscopy
Contact and non-contact based atomic force microscopy (AFM) approaches have been extensively utilized to explore various nanoscale surface properties. In most AFM-based measurements, a concurrent electrostatic effect between the AFM tip/cantilever and sample surface can occur. This electrostatic effect often hinders accurate measurements. Thus, it is very important to quantify as well as remove...
متن کاملReversible short-range electrostatic imaging in frequency modulation atomic force microscopy on metallic surfaces
The mechanism of atomic-scale image formation in non-contact AFM on metallic surfaces is analysed using total-energy pseudopotential calculations. Depending on the tip–apex configuration, we find two different imaging modes. Both clean and metal contaminated Si tips provide atomic resolution arising from the very strong covalent tip–sample interaction, in striking similarity with the imaging me...
