Abstract

A study of the surface structure and electronic properties of (010) KGd_0.95Nd_0.05(WO₄)₂ (Nd:KGW) using RHEED analysis and XPS is presented. It is shown that Nd doping has a negligible effect on the core levels of the basic elements. A bombardment of the Nd:KGW crystal with 3-keV Ar ions results in surface amorphization accompanied by the generation of tungsten ions in lower valence states.
