摘要：

By means of the Scanning Tunneling Microscope (STM), we have purposely created monolayer-deep vacancy islands on a Cu (111) surface covered with submonolayer amounts of Co and observed their motion in real time at room temperature. A quantitative evaluation of their random walk allows us to obtain their diffusion coefficient.
