scanning-electrochemical microscopy
Microscopy where an electrode probe is positioned very close to the surface of the specimen (in the near-field). The surface is mechanically scanned by the electrode in a raster scan and the height required by a feedback loop in order to maintain a constant electrical conductance between the electrode and the specimen is recorded as a function of position.
