1. Describe the different process of electron-atom interaction!
2. What information can we receive from a TEM? Describe the corresponding modes.
3. Why we use electrons to probe matter interaction?
4. What is the best resolution in a microscope? Estimate!
5. Name the bases which lead to the discovery of electron microscopy. Write the corresponding formulars.
6. Can we apply the Abbe imaging formation process, developed for light in TEM? Explain! What is the primary image? How we can calcuate it?
7. What is the spherical aberration Cs? Why we cannot have a negative Cs value for electro-magnetic and electrostatic lenses? Explain.
