scanning probe microscopy


scanning probe microscopy
Methods for visualizing surfaces at microscopic scale that rely on moving a tiny probe over a surface (usually in an x-y scan), and recording some property of interest (current, force) at each coordinate. These techniques have the ability to resolve detail down to single atoms. See also scanning tunnelling microscopy and atomic force microscopy.
