Uva Virtual Lab: Scanning Electron Microscope (Sem)

In this microscope worksheet, students use an on line site to answer questions about how a Scanning Electron Microscope works. They also conduct a virtual microscope activity where they view ten specimens and identify what each is.

Check out this online lab to recognize what an SPM is and how it functions.

Find a description of the operation of Nanosurf Inc's "easyScan" scanning tunneling microscope (STM). Virtual reality is used to take apart the microscope and show how electron tunneling is used to measure the shape of sample surfaces...

At this resource you'll find everything from a mosquito head to a fly foot, from a dentist's drill to toilet paper! These and just about everything in between as seen through a scanning electron microscope.

This page describes the operation of Nanosurf Inc's "easyScan" atomic force microscope (AFM). Virtual reality is used to take apart the microscope and show how a laser controlled feedback loop allows the probe to measure the shape of a...

SCALPEL stands for Scattering with Angular Limitation Projection Electron beam Lithography. It is a new technique for creating patterns with extremely small features in microelectronic circuits. Electrons are projected onto a "mask."...

These pages use JavaScript to create the illusion of controlling a Scanning Electron Microscope (SEM).

Scanning Probe Microscopes position their sensing tips to precisions better than 10-10 meters (the size of a single atom!). This incredible control is based on the use of "piezoelectric crystals." These materials bend or shrink in the...

View a video or a click-through a slideshow to find out how the SEM works. In addition, find an interesting gallery of magnified images captured with an SEM, links to related sites, and a teacher resource section.
