Modern commercial scanning electron microscopes (SEMs) are equipped with a cathode lens mode, which enables us to use extremely low landing energies of the primary electrons. There are many benefits of the low energy electron microscopy and this technique has been recognized as an important tool for the characterization of advanced steels. At lower energies, the contrast in SEM micrographs is more and more influenced by the surface and its state. In this study, we investigated the effect of a native oxide layer on the contrast in SEM images of a mild steel surface obtained at energies from 5 keV up to units of eV shows a series of the SEM micrographs of mild steel collected by anin-house designed ultra-high vacuum scanning low energy electron microscope (UHV SLEEM). The micrographs of the same area of view were obtained with various landing energies of the primary beam.
