What is Electron Microscopy? - UMass Chan Medical School
WebBackscattered electrons (BSE) and secondary electrons (SE) are the most important signals for image recording. A knowledge of the dependence of the backscattering coefficient η … Webeither the primary beam, or the backscattered secondary electrons The atom relaxes by filling the hole with an electron coming from an outer level, in the example shown as L1. Secondary electrons are electrons generated as ionization products. They are called 'secondary' because they are generated by other radiation (the primary radiation). This radiation can be in the form of ions, electrons, or photons with sufficiently high energy, i.e. exceeding the ionization potential. Photoelectrons can … See more Secondary electrons are also the main means of viewing images in the scanning electron microscope (SEM). The range of secondary electrons depends on the energy.
