Radial-histogram transform of scanning-probe-microscope images.
Physical Review B-Condensed Matter, vol.55, no.4, 15 Jan. 1997, pp.2535-42. Publisher: APS through AIP, USA.
A transform is described for analyzing scanning-probe-microscope images. This radial-histogram transform is shown to contain useful information for ascertaining the structure of an object in a scanning-probe-microscope image. The radial-histogram transform also allows quantitative assessment of tip dilation effects. The utility of the transform is illustrated by analyzing a noncontact atomic force microscope image of a nanometer size Au cluster supported on a mica substrate. Using the radial-histogram transform, detailed information about the faceting, structure, and orientation of the supported nanometer-size cluster is obtained. (28 References).
