Abstract

The variation of the characteristic X-ray emission from a thin crystal with crystallographic direction of the incident electron beam has proved to be a powerful effect for the determination of the crystallographic position of atoms with similar atomic numbers and low concentrations of atoms. The studies of a Al₂ZnO₄ spinel containing 3% Fe and 0.3% Mn, i.e. small concentrations of neighbours in the periodic system, will be presented. It is concluded that 62±2% of the Fe atoms and 97±10% of the Mn atoms are in tetrahedral positions. The high sensitivity of the method suggests that it is possible to determine the position of a monolayer or less of adatoms on a crystal surface. This possibility is discussed.
