Abstract

Monatomic iron (Fe) nanowires were fabricated on the vicinal Au(111) surfaces and the surface electronic structures were examined. Monatomic rows were clearly observed by the scanning tunneling microscopy (STM). Angular distributions of photoemission spectra were obtained by angle-resolved photoemission spectroscopy (ARPES) measurements before and after the formation of Fe nanowires. The results show that the 3d bands of the fe nanostructures show 1D electronic features at the coverages lower than ∼0.6 ML, which seems to be reinforced by the quasi-1D electronic nature of the vicinal Au(111) substrate.
