Adatom self-diffusion on Pt (100) surface by an ad-dimer migrating

导出

摘要 We study the self-diffusion of adatom on Pt(100) surface by molecular dynamics. The metal is modeled by the surface embedded-atom potential. Besides the conventional concerted exchange mechanism, a new exchange mechanism in which an ad-dimer diffuses by a concerted motion of three atoms is observed. The importance is that it could become a dominant diffusion mechanism in some cases. We study the self-diffusion of adatom on Pt(100) surface by molecular dynamics.
