报导了一种用于扫描深外显微镜（SPM）研究的原子级平整全基底的制备方法．采用这种方法，得到了25um2范围内，膜的平均粗糙度小平0.4nm的原子级平整基底，并且得到金以（111）面取向在云母表面沉积的实验证据，同时使用电化学循环伏安法和X光电子能谱对这种膜的自组装性能进行了考察．
A method of preparing an atomically flat whole substrate for scanning deep-space microscopy (SPM) studies is reported. In this way, atomically flat substrates with a mean roughness of 0.4 μm were obtained in the region of 25 μm 2, and experimental evidence of the gold (111) orientation on the mica surface was obtained. At the same time, electrochemical cyclic voltammetry And X-ray photoelectron spectroscopy of self-assembly of this film were investigated.
