Abstract
A novel method is proposed to measure the charging potential of dielectric targets under medium energy electron irradiation in a scanning electron microscope. The method is based on the measurement of backscattered electron signals by standard semiconductor or scintillation detectors. The signal is pre-calibrated by grey scale levels on the SEM screen. The detector signal is made up with backscattered and secondary electrons which are accelerated in the electric field created above the dielectric surface under irradiation.
期刊介绍:
Micron is an interdisciplinary forum for all work that involves new applications of microscopy or where advanced microscopy plays a central role. The journal will publish on the design, methods, application, practice or theory of microscopy and microanalysis, including reports on optical, electron-beam, X-ray microtomography, and scanning-probe systems. It also aims at the regular publication of review papers, short communications, as well as thematic issues on contemporary developments in microscopy and microanalysis. The journal embraces original research in which microscopy has contributed significantly to knowledge in biology, life science, nanoscience and nanotechnology, materials science and engineering.
