利用扫描隧道显微镜（STM）针尖在局部高电场作用下，在Au（111）表面产生了规则的纳米级指状条纹。指状物是一个原子层高，4-8 nm宽和超过200 nm长。发现金手指指向三个等价的（110）方向之一，并且手指的两个平行侧边由紧密堆积的原子组成。纳米级指状条纹的数量、位置和方向可以通过改变STM扫描中使用的参数来控制。纳米级的指状条纹是潜在的有用的作为一个有前途的纳米结构模板。
Regular nanoscale finger-like stripes have been produced on the Au(111) surface using a scanning tunnelling microscopy (STM) tip with a high local electric field. The fingers are one atomic layer high, 4-8 nm wide and more than 200 nm long. The gold fingers are found to point in one of the three equivalent (110) directions, and the two parallel side edges of the fingers consist of close-packed atoms. The number, site and direction of the nanoscale finger-like stripes can be controlled by varying the parameters used in STM scans. The nanoscale finger-like stripes are potentially useful as a promising nanostructured template.
