Characterising heavy-tailed networks using q-generalised entropy and q-adjacency kernels
Ismo T. Koponen, Elina Palmgren, Esko Keski-Vakkuri
Heavy-tailed networks, which have degree distributions characterised by slower than exponentially bounded tails, are common in many different situations. Some interesting cases, wh…
Diffusion and submonolayer island growth during hyperthermal deposition on Cu(100) and Cu(111)
M. O. Jahma, M. Rusanen, A. Karim +3
We consider the influence of realistic island diffusion rates to homoepitaxial growth on metallic surfaces using a recently developed rate equation model which describes growth in…
Morphology of ledge patterns during step flow growth of metal surfaces vicinal to fcc(001)
M. Rusanen, I. T. Koponen, T. Ala-Nissila +2
The morphological development of step edge patterns in the presence of meandering instability during step flow growth is studied by simulations and numerical integration of a conti…
Meandering instability of curved step edges on growth of a crystalline cone
M. Rusanen, I. T. Koponen, T. Ala-Nissila
We study the meandering instability during growth of an isolated nanostructure, a crystalline cone, consisting of concentric circular steps. The onset of the instability is studied…
Instability and wavelength selection during step flow growth of metal surfaces vicinal to fcc(001)
M. Rusanen, I. T. Koponen, J. Heinonen +1
We study the onset and development of ledge instabilities during growth of vicinal metal surfaces using kinetic Monte Carlo simulations. We observe the formation of periodic patter…
Island diffusion on metal fcc(100) surfaces
J. Heinonen, I. Koponen, J. Merikoski +1
We present Monte Carlo simulations for the size and temperature dependence of the diffusion coefficient of adatom islands on the Cu(100) surface. We show that the scaling exponent…
