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…
Nonlinear Driven Response of a Phase-Field Crystal in a Periodic Pinning Potential
C. V. Achim, J. A. P. Ramos, M. Karttunen +4
We study numerically the phase diagram and the response under a driving force of the phase field crystal model for pinned lattice systems introduced recently for both one and two d…
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…
