Abstract:
A goniometer for performing scanning probe microscopy on a substrate surface, the goniometer comprising:a cantilever, having a cantilevered end and a supported end,a tip disposed at the cantilevered end of the cantilever, anda block disposed at the supported end of the cantilever, the block having at least one pair of piezoelectric layers, a pair of electrodes disposed about each individual piezoelectric layer, and a first insulating material disposed between the individual electrodes for insulating the individual electrodes from each other; whereby the individual piezoelectric layers of a pair of piezoelectric layers are deformed at different rates upon application of a potential difference across the individual electrodes of at least one of the pairs of electrodes, resulting in a deformity of the block and tilting of the cantilever and tip connected therewith.
