AuN films - structure and chemical binding

AuN films were produced on 304 stainless steel using an arc‐pulsed – assisted plasma physical vapor deposition system. The deposition was performed using an Au target in a nitrogen atmosphere at different pressures. The films were characterized using x‐ray photoelectron spectroscopy and x‐ray diffra...

Description
Summary:AuN films were produced on 304 stainless steel using an arc‐pulsed – assisted plasma physical vapor deposition system. The deposition was performed using an Au target in a nitrogen atmosphere at different pressures. The films were characterized using x‐ray photoelectron spectroscopy and x‐ray diffraction. A 398.1‐eV binding energy was observed and assigned to gold nitride species. The x‐ray diffraction patterns displayed a crystallographic structure that corresponded to the Au‐fcc phase with broad diffraction lines. The observed widening of the Bragg diffraction lines (rocking curves) can be attributed to the presence of interstitial nitrogen atoms in the Au‐fcc structure.
