eng Abstract:
Specimen observation at a low accelerating voltage of the electron beam (around 1kV) is a new and attractive technique of scanning electron microscopy. While detection to the signal of secondary electrons (SE) with the help of the scintillation-photomultiplier system described by Everhart-Thornley does not depend on the primary beam energy, the detection of backscattered electrons (BSE), having their energy only a bit lower than energy of the beam, is limited by a low sensitivity of semiconductor or channel plate detectors to channel plate detectors to electrons of energy below 2 keV.
