Valence Band ofMg2Sn Determined by Auger and Photoemission Spectroscopy

Abstract
It is shown that Auger spectroscopy can be used to determine the density of valence states in compound semiconductors. We determined the density of valence states by this method in Mg2Sn and find it in basic agreement with those which we obtained by x-ray-and uv-induced photoelectron spectroscopy. A comparison is made with the calculated Mg2Sn valence band. The Mg2Sn valence band obtained by Auger spectroscopy (involving the KL transition in Mg) is contrasted with the analogous spectrum for Mg metal.
