Abstract
A supported probe device that has a probe tip and probe body, the probe body having a sample facing surface and an opposing surface. The probe tip and a first electrode are on the sample facing surface. A second electrode is present on the probe body opposing surface. A third electrode is spaced from the second electrode, so that the second electrode is between the third electrode and the probe body. A first DC voltage source is electrically coupled to the first electrode, as is a first sensing circuit. A second DC voltage source is electrically coupled to the second electrode, and an AC voltage source electrically coupled to the third electrode. The probe body may be cantilevered.
