Growth and Oxidation of Silicene Nano-Ribbons on Ag(110)

ORAL

Abstract

Scanning tunneling microscopy (STM) and high resolution photoemission electron spectroscopy (HR-PES) are used to study the growth and the oxidation of silicene nano-ribbons (NRs) on Ag(110) substrate. Deposition of silicon on Ag(110) induces a self-assembled silicene NRs having a (2x5) superstructure. We find out that the NRs are not reactive to molecular oxygen. However for a certain bias, the STM tip can dissociate the molecular oxygen which reacts then immediately with the NRs.
