Low voltage scanning electron microscopy [PDF]

Journal of Microscopy, 1984
SUMMARYThe scanning electron microscope (SEM) is usually operated with a beam voltage, V0, in the range of 10–30 kV, even though many early workers had suggested the use of lower voltages to increase topographic contrast and to reduce specimen charging and beam damage. The chief reason for this contradiction is poor instrumental performance when V0=1–3
