Abstract

A dedicated ultra-high-vacuum 100 kV scanning transmission electron microscope has been used to characterize the electron-beam-induced damage which occurs on the surfaces of rutile crystals as a result of extensive electron irradiation. Biased secondary electron images from the entrance and exit surfaces indicate that the latter surface is damaged at a substantially greater rate than the former. It is concluded that knock-on collisions play an important role in the observed exit surface sputtering.
