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.

Frontiers in Scanning Probe Microscopy
30 Nov 2006 |
From October 4- 6, 2006 the Birck Nanotechnology Center at Purdue University hosted a three day focused workshop on cutting edge SPM techniques that are under development throughout the world.The three day workshop featured thematically arranged invited talks. The workshop themes are broadly...
A Primer on Scanning Tunneling Microscopy (STM)
04 Apr 2006 | | Contributor(s):: Ron Reifenberger
Scanning Probe Microscopes and their remarkable ability to provide three-dimensional maps of surfaces at the nanometer length scale have arguably been the most important tool in establishing the world-wide emergence of Nanotechnology. In this talk, the fundamental ideas behind the first scanning...
Scanning Probe Microscope Piezoelectric Crystals
16 Nov 2005 | | Contributor(s)::
In this resource we disassemble the piezoelectric assembly of a scanning probe microscope. At its core is a white cylinder of the piezoelectric material. If you look closely, it has a granular texture that reflects the fact that it is actually made up of many small crystals.
Scanning Probe Microscope Operation
Scanning Probe Microscopes (SPMs) include Atomic Force Microscopes (AFMs) and Scanning Tunneling Microscopes (STMs or STEMs). They are the only instruments in widespread use that can actually "see" single atoms! You can skim this resource quickly to learn the general concepts of SPMs, or you can...
Introduction to Molecular Conduction
21 Jul 2005 | | Contributor(s):: Ferdows Zahid, Magnus Paulsson, Avik Ghosh, Supriyo Datta
A scanning probe microscope brushes the tips of molecules rising up from a gold substrate. After making contact, the probe measures a very strange current-voltage relationship--linear portions separated by flat spots or sharp increases. Definitely not Ohm's law. Is the experiment correct?...
What is a Nanometer?
02 Apr 2005 | | Contributor(s)::
Join Laura and Martin on a wild ride through the milliworld and the microworld to reach the nanoworld. Along the way, they discover how small a nanometer truly is.
Nanotechnology is not just a topic for physicists, chemists, and engineers. Laura explains the important role of biologists in this field, and shows how they may help provide clues to molecular assembly techniques.
Scanning Probe Microscopes
15 Mar 2005 | | Contributor(s)::
Laura explains how scanning probe microscopes can be used to create images of small devices, molecules, and even atoms! A large-scale version of the scanning probe microscope is built out of Legos to show the basic principles.
Feasibility of Molecular Manufacturing
14 Mar 2005 | | Contributor(s)::
Martin and Laura have an interesting debate about the feasibility of Molecular Manufacturing. Can molecular assemblers be developed to create new materials, new devices, and even macroscopic objects? Find out... If Martin ever wakes up!
Nanomanufacturing: Top-Down and Bottom-Up
Martin presents an overview of nanomanufacturing techniques, explaining the difference between top-down and bottom-up approaches.
