Week 5 RET

We go to see how and SES- Scanning Electron Microscope works this week. Basically, it is a microscope that uses a beam of electrons that interact with the atoms that make up the sample that is being viewed. Signals are produced that contain information about the sample's surface, composition and other properties. We looked at our photolithography nano-pattern and viewed the imperfections as seen in this picture. Can you see what magnification this is at? Can you see what size this particle is?
