Stress release mechanisms for Cu on Pd(111) in the submonolayer and monolayer regimes
J. Jalkanen, G. Rossi, O. Trushin +3
We study the strain relaxation mechanisms of Cu on Pd(111) up to the monolayer regime using two different computational methodologies, basin-hopping global optimization and energy…
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…
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…
First-principles calculations of spin spirals in Ni2MnGa and Ni2MnAl
J. Enkovaara, A. Ayuela, J. Jalkanen +2
We report here non-collinear magnetic configurations in the Heusler alloys Ni2MnGa and Ni2MnAl which are interesting in the context of the magnetic shape memory effect. The total e…
