| Research Abstract |
Surface defects on Au(111) formed by ion irradiation were observed at an atomistic resolution by scanning tunnel microscope combined with an ion accelerator. The step-height method with this equipment enabled to identify the nature of defects and to quantify their size. Molecular simulations were conducted with equivalent conditions to the experiments, and it was clarified that the results were reasonably consistent with the experimental observations. This comparison attested the validity of the simulations under non-equilibrium states.
