Molecular Beam Epitaxy
4.0 out of 5 stars
16 Nov 2005 | Animations | Contributor(s): John C. Bean
Microelectronic devices are made by repeating two steps: 1) Depositing a thin uniform layer of material; 2) Then using a photographic process to pattern and remove unwanted areas of that layer.
Scanning Electron Microscope
5.0 out of 5 stars
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...
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...
