Study of the island morphology at the early stages of Fe/Mo(110) MBE growth
Dmytro Goykolov, Miroslav Kotrla
We present theoretical study of morphology of Fe islands grown at Mo(110) surface in sub-monolayer MBE mode. We utilize atomistic SOS model with bond counting, and interactions of…
Interplay of Strain Relaxation and Chemically Induced Diffusion Barriers: Nanostructure Formation in 2D Alloys
T. Volkmann, F. Much, M. Biehl +1
We study the formation of nanostructures with alternating stripes composed of bulk-immiscible adsorbates during submonolayer heteroepitaxy. We evaluate the influence of two mechani…
Effects of atomic interactions in two component submonolayer growth
Miroslav Kotrla, Joachim Krug
We discuss effects of the different chemical bondings on the island morphology and on the island density scaling in two-component submonolayer growth. Different regimes depending o…
Effects of adsorbates on submonolayer growth
Miroslav Kotrla, Joachim Krug, Pavel Smilauer
The effects of adsorbates on nucleation and growth of two-dimensional islands is investigated by kinetic Monte Carlo simulations and rate equation theory. The variation of island m…
Energy barriers for diffusion on stepped Pt(111) surface
F. Maca, M. Kotrla, O. S. Trushin
We performed molecular statics calculations of energy barriers for adatom moves in the vicinity of steps on Pt(111) surface. We used the semi-empirical many-body Rosato--Guillope--…
