摘要：
Silicene, the new allotropic form of silicon, represents an interesting promise for future new nanostructured materials. Here, we investigate the room temperature oxidation of a one-dimensional grating of silicene nanoribbons grown on a Ag(1 1 0) surface by high-resolution Si 2p core level photoemission spectroscopy and low-energy electron diffraction observations. The oxidation process starts at very high oxygen exposures, about 104 times higher than on the clean Si(1 1 1) 7 x 7 surface, which demonstrates the low reactivity of silicene to molecular oxygen. Ar+ sputtering produces defects, which enhance the oxidation uptake.
