用扫描隧道显微镜对金(111)表面的金原子进行了逐层去除。这一过程是通过表面十二硫醇分子的化学吸附自组装单分子层(SAM)实现的，这导致最上面两层金原子之间的结合强度降低。金原子和相关的吸附分子被STM针尖剥离并横向移动，修饰区域的大小(降至类似于10×10 nm)或多或少由扫描大小决定。(C)2002年美国物理研究所。
Layer by layer removal of gold atoms from the (111) surface of gold has been performed using the scanning tunneling microscope. The process is made possible by a chemisorbed self-assembled monolayer (SAM) of dodecanethiol molecules on the surface, which gives rise to a reduced bonding strength between the top two layers of gold atoms. The gold atoms and associated adsorbed molecules are peeled off and displaced laterally by the STM tip, and the size of the modified area (down to similar to10x10 nm) is more or less determined by the scan size.
