Reflection electron microscopy of epilayers grown by molecular beam epitaxy

Abstract
Reflection electron microscopy has been used lo obtain surface images of interfaces in epilayers grown by molecular beam epitaxy (MBE). The image contrast arises from differences in structure factors for the surface reflections used in the imaging. The technique is potentially a powerful tool for the study of semiconductor devices grown by MBE, by metal organic chemical vapour deposition, and by liquid-phase epitaxy as it yields cross-sectional images of cleavage planes.
