Investigation of single-domain Au silicide nanowires on Si(110) formed for Au coverages in the monolayer regime

Abstract The self-organized formation of single domain Au silicide nanowires is observed on Si(110). These nanowires are analysed using scanning tunnelling microscopy (STM) and spectroscopy (STS) as well as photoemission spectroscopy (PES). Core-level PES is utilised to confirm the formation of Au s...
