Scanning Probe Microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. An image of the surface is obtained by mechanically moving the probe in a raster scan of the specimen, line by line, and recording the probe-surface interaction as a function of position.

SPMW A fresh look to amplitude-modulation AFM: Force minimization, interaction measurement, and the quest for high resolution
0.0 out of 5 stars
03 Jul 2007 | Online Presentations | Contributor(s): Udo D. Schwarz
Frequency modulation atomic force microscopy (FM-AFM) has been able to deliver high-resolution atomic-scale images in ultrahigh vacuum for over one decade. In addition, there have been recent...
Orbital Mediated Tunneling in a New Unimolecular Rectifier
22 Jun 2007 | Online Presentations | Contributor(s): Robert Metzger, NCN SLC@Northwestern
In 1997 we showed that hexadecylquinolinium tricyanoquinodimethanide is a unimolecular rectifier, by scanning tunneling microscopy and also as a Langmuir-Blodgett (LB) monolayer, sandwiched...
SPMW AFM at Video Rate and Beyond
