Goal of the courseThis course on Electron Microscopy (E/M) aims to introduce students of the Physics and other departments to the basic concepts of E/M starting from basic principles of Geometric and Physical optics and extending to study and operational principles of the Scanning Electron Microscope (SEM), the Transmission Electron Microscope (TEM) and the Atomic Force Microscope (AFM), including pumping and vacuum procedures and fundamentals of image formation. It also covers the subjects of qualitative and quantitative microanalysis (ZAF method) and electron diffraction. The class is concluding with an “on-hands” lab practice of students on techniques for the preparation and observation/analysis of various inorganic and organic samples.
SyllabusGeneral principles: Geometric and Physical optics- Imaging-Lenses- Simple/ stereoscopic microscope- Apertures- Resolution/Airy disc.
