Atomic-scale self-organization of Fe nanostripes on stepped Cu(111) surfaces — •Nikolay N. Negulyaev1, Valeri S.

Growth of Fe nanostripes on a vicinal Cu(111) surface is investigated on the atomic scale performing molecular dynamics and kinetic Monte Carlo simulations [1]. We involve in our study the kinetic mechanisms of incorporation of Fe atoms into the stepped Cu(111) surface. The atomic processes responsible for the interlayer mass transport and the self-assembly of 1 ML high Fe stripes are identified. The role of temperature is revealed. We demonstrate that strain relaxations at steps have a strong impact on the self-assembly of one-dimensional Fe atomic structures on vicinal Cu(111).
