The part of SEM that is responsible for the production of electrons. * Electron guns Condenser lens Secondary detector Electron beam A surface analysis technique used for determining elemental composition on surfaces of solid samples. AFM SEM XRD SIMS XPS A surface analysis technique that uses a cantilever to scan over a region of interest. The cantilever deflects towards or away from the surface due to the attractive and repulsive forces with the sample. AFM SEM XRD XPS SIMS
