Scanning Electron Microscope
out of 5 stars
16 Nov 2005 |
This resource describes a scanning electron microscope (SEM). It includes detailed depictions of how the electron beam is focused and used to create hugely magnified images of experimental specimens.
Scanning Probe Microscope Piezoelectric Crystals
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...
Scanning Probe Microscopes
15 Mar 2005 |
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 |
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!
