Abstract
A method for determining a value of a local contact potential difference by noncontact atomic force microscopy. For one or more cantilever positions above a surface of a sample: i) determining two distinct voltage values of DC voltage applied between an oscillating cantilever and the sample, and ii) determining, by one or more processors, a value of a local contact potential difference based, at least in part, on the two distinct voltage values that were determined.
