我们开发了一种通过自组织在钨表面碳化物 W(110)/C-R(15x3) 上制造一维图案超薄金覆盖层的技术。研究发现，在 R(15x3) 碳超结构上沉积 1-3 个单原子金层，然后在 600 摄氏度下退火，会形成金覆盖层，其表面以约 30 A 的周期进行一维重构。我们通过电子衍射、扫描隧道显微镜和光电子能谱来表征该系统，以揭示所创建的纳米图案的化学成分。最终，证明了支撑在这种图案化金薄膜上的镍纳米线的自组织性。
We developed a technique to fabricate one-dimensionally patterned ultrathin Au overlayers on the tungsten surface carbide W(110)/C-R(15x3) by self-organization. It was found that deposition of 1-3 monoatomic layers of Au on the R(15x3) carbon superstructure and subsequent annealing at 600 degrees C lead to the development of a Au overlayer the surface of which is one-dimensionally reconstructed with a periodicity of about 30 A. We present a characterization of this system by electron diffraction, scanning tunneling microscopy, and photoelectron spectroscopy to reveal the chemical composition of the created nanopattern. Eventually, the self-organization of Ni nanowires supported on such patterned Au film is demonstrated.
