Electronic properties of H on vicinal Pt surfaces: A first-principles study
T. Vehviläinen, P. Salo, T. Ala-Nissila +1
In this work, we use the first-principle density-functional approach to study the electronic structure of a H atom adsorbed on the ideal Pt(111) and vicinal Pt(211) and Pt(331) sur…
Two Approaches to Dislocation Nucleation in the Supported Heteroepitaxial Equilibrium Islanding Phenomenon
J. Jalkanen, O. Trushin, K. Elder +3
We study the dislocation formation in 2D nanoscopic islands with two methods, the Molecular Static method and the Phase Field Crystal method. It is found that both methods indicate…
Equilibrium Shape and Size of Supported Heteroepitaxial Nanoislands
J. Jalkanen, O. Trushin, E. Granato +2
We study the equilibrium shape, shape transitions and optimal size of strained heteroepitaxial nanoislands with a two-dimensional atomistic model using simply adjustable interatomi…
Thermal fluctuations and phase diagrams of the phase field crystal model with pinning
J. A. P. Ramos, E. Granato, C. V. Achim +3
We study the influence of thermal fluctuations in the phase diagram of a recently introduced two-dimensional phase field crystal model with an external pinning potential. The model…
Diffusion of small two-dimensional Cu Islands on Cu(111)
Altaf Karim, Ahlam N. Al-Rawi, Abdelkader Kara +3
Diffusion of small two dimensional Cu islands (containing up to 10 atoms) on Cu(111) has been studied using the newly developed self-learning Kinetic Monte Carlo SLKMC method. It i…
Equilibrium shape and dislocation nucleation in strained epitaxial nanoislands
J. Jalkanen, O. Trushin, E. Granato +2
We study numerically the equilibrium shapes, shape transitions and dislocation nucleation of small strained epitaxial islands with a two-dimensional atomistic model, using simple i…
