我们报道了在相邻铜表面上制备周期性纳米条纹。对于所研究的Cu(n,n,n−1)表面[n= 4,3,2],观察到了由Cu(111)和Cu(110)-O(2×1)面组成的周期性纳米条纹的规则单原子台阶表面的氧诱导介观刻面。这些纳米条带的宽度和热稳定性随着初始邻位表面的台阶长度而增加。对于Cu(443)、Cu(332)和Cu(221),分别获得50、20和12 nm的条带宽度。而在Cu(221)上,纳米条纹在450 K以上消失,而在Cu(443)上,纳米条纹在800 K以下是稳定的。对于后者的表面,纳米结构被发现是异常稳定的,可以观察到非原位原子力显微镜在环境条件下。
We report the preparation of periodic nanostripes on vicinal copper surfaces. For the investigated Cu(n,n,n−1) surfaces [n=4,3,2], an oxygen-induced mesoscopic faceting of the regular monoatomic stepped surfaces into periodic nanostripes consisting of Cu(111) and Cu(110)–O(2×1) facets is observed. The width and thermal stability of these nanostripes increase with the terrace length of the initial vicinal surfaces. Stripe widths of 50, 20, and 12 nm were obtained for Cu(443), Cu(332), and Cu(221), respectively. Whereas on Cu(221) the nanostripes disappear above 450 K, they are stable up to 800 K on Cu(443). For the latter surface, the nanostructures are found to be unusually stable and could be observed ex situ by atomic force microscopy under ambient conditions.
