Abstract

A newly developed method is reported here for taking Kikuchi electron diffraction patterns using conventional low-energy electron diffraction facilities. Kikuchi electron forward-scattering diffraction patterns from a single crystal Cu(111) surface have been obtained using a hemispherical rear-view LEED screen and camera interfaced to a computer. The new technique allows us to take a set of Kikuchi electron diffraction images over a wide primary energy range (50-950 eV in steps of 5 eV) within a couple of hours. With this technique we show that the Kikuchi electron, like the photoelectron and Auger electron, can be considered as being emitted from inside the crystal.
