In scanning electron microscopy visual inspection of the surface of a material utilizes signals of two types, secondary and backscattered electrons. Secondary and backscattered electrons are constantly being produced from the surface of the specimen while under the electron beam however they are a result of two separate types of interaction.
A fine electron probe is scanned over the specimen. Various detectors (Secondary Electron (SE), Back Scattered Electron (BSE), X-Ray, Auger Electron (AE) etc.) pick up the signals. The amplified output of a detector controls the intensity of the electron beam of a CRT (synchronized scanning) of the pixel of display Scanning Electron Beam.
Why electron microscopy • Primary reason: Spot size DeBroglie wavelength of a particle If speeds are large or total acceleration voltage is close to rest mass of particle You should better use relativistic formulas for energy, momenta etc.
