Abstract
The InAs(111)2x2 and InAs(-1-1-1)1x1 surfaces have been studied with high resolution core level spectroscopy. For the InAs(-1-1-1)1x1 surface both the In 4d and the As 3d core levels display strong surface core level shifts, while for the InAs(111)2x2 surface only the In 4d level shows a detectable surface shift. The results indicate that the InAs(-1-1-1)1x1 surface is relaxed, with atom layer displacement extending to subsurface layers. Unexpectedly, we find no surface shifted anion core level for the InAs(111)2x2 surface.
