Abstract
A force scanning probe microscope (FSPM) and associated method of making force measurements on a sample includes a piezoelectric scanner having a surface that supports the sample so as to move the sample in three orthogonal directions. The FSPM also includes a displacement sensor that measures movement of the sample in a direction orthogonal to the surface and generates a corresponding position signal so as to provide closed loop position feedback. In addition, a probe is fixed relative to the piezoelectric scanner, while a deflection detection apparatus is employed to sense a deflection of the probe. The FSPM also includes a controller that generates a scanner drive signal based on the position signal, and is adapted to operate according to a user-defined input that can change a force curve measurement parameter during data acquisition.
