The Pd-H system revisited: an XPS and UPS study

Abstract

The authors have explored the possibility of using H2+ ion implantation to produce a Pd-H system for electron spectroscopic studies. This has been achieved by in situ implantation in a VG Scientific ESCA-3 MkII electron spectrometer using the AG-2 sputter ion gun. XPS and UPS studies were carried out on these samples. The results are in agreement with band-structure calculations and with XPS and UPS studies on the Pd-H system prepared by conventional methods.
