Introduction to Electron Microscopy
Scanning Electron Microscopes (SEMs) and Transmission Electron Microscopes (TEMs) differ from conventional light microscopes in that they employ electrons rather than photons to irradiate material and produce images.
What can the instruments do for us?
They allow us to see things at the micro, nano and sub-nanometre scales.
The material being studied should be a solid material and be able to withstand the energy of the electrons being directed at it.
Electron microscopes can analyse most materials, including:
- Metals and metal compounds
- Rocks and minerals
- Plant and animal materials
- Some liquids
