- Background information - What is transmission electron microscopy?
- It allows detailed micro-structural examination through high-resolution and high magnification imaging.
- Combining images
- Concepts - introduction
- The use of electrons has an impact on image resolution and absence of colour, and explains the two dimensional nature of micrographs (images/photographs).
- Diffraction patterns
- Electron gun
- Image appearance
- Image formation basics
- This two-step process forms the basis of image formation during high-resolution transmission electron microscopy (HRTEM).
- Image types
- Images from electrons
- Click on any of the images on this page to see them at their full resolution.
- Inorganic sample/physical science specimen preparation for TEM
- Machine operating procedures
- This involves imaging for high resolution (HREM), diffraction and sample tilting, and for microanalysis [but for this see the module on microanalysis].
- Machine settings
- Problems with lenses: aberrations
- Spherical and chromatic aberrations limit the resolution of conventional electron microscopes.
- Resolution
- Definitions resolution the ability to distinguish closely spaced points as separate points.
- Specimen/sample chamber
- This is important for obtaining precisely oriented diffraction patterns and high resolution images.
- Spherical aberration
- This lens defect limits the resolution of modern TEM.
- The electron wavelength
- The higher the accelerating voltage, the smaller the wavelength of the electrons and the higher the possible achievable resolution.
