Global transition path search for dislocation formation in Ge on Si(001)
Emile Maras, Oleg Trushin, Alexander Stukowski +2
Global optimization of transition paths in complex atomic scale systems is addressed in the context of misfit dislocation formation in a strained Ge film on Si(001). Such paths con…
The crossover from collective motion to periphery diffusion for 2D adatom-islands on Cu(111)
Altaf Karim, Abdelkader Kara, Oleg Trushin +1
The diffusion of two dimensional adatom islands (up to 100 atoms) on Cu(111) has been studied, using the self-learning Kinetic Monte Carlo (SLKMC) method [1]. A variety of multiple…
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…
Off-Lattice Self-Learning Kinetic Monte Carlo: Application to 2D Cluster Diffusion on the fcc(111) Surface
Oleg Trushin, Handan Yildirim, Abdelkader Kara +1
We report developments of the kinetic Monte Carlo (KMC) method with improved accuracy and increased versatility for the description of atomic diffusivity on metal surfaces. The on-…
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…
