Abstract:
An imaging method of atomic force microscopy comprising:substantially continuously monitoring displacement of a cantilever relative to a specimen at multiple points within an area; measuring a specimen profile height at a point within the area by moving a probe tip on the cantilever in discrete, incremental amounts towards the specimen until a contact with the specimen occurs at the point and storing a value related to an increment in which the contact occurs, and following contact, measuring an adhesion force at the point by driving the probe tip away from the specimen by incrementally applying an increasing magnetic force to the cantilever until the probe tip releases from the specimen and storing a value related to a magnetic force increment in which the probe tip released; and concurrent with the measuring of the specimen profile height, displaying the profile height and concurrent with the release of the probe tip, displaying the adhesion force for each of the points in the area contacted by the probe tip.
