Cluster Diffusion and Coalescence on Metal Surfaces: applications of a Self-learning Kinetic Monte-Carlo method
Talat S. Rahman, Abdelkader Kara, Altaf Karim +1
The Kinetic Monte Carlo (KMC) method has become an important tool for examination of phenomena like surface diffusion and thin film growth because of its ability to carry out simul…
Comparative study of adatom manipulation on several fcc metal surfaces
Chandana Ghosh, Abdelkader Kara, Talat S. Rahman
For a set of fcc metals our total energy calculations, based on many body potentials, show that activation barriers for lateral manipulation of an adatom at a step edge depend on t…
First-principles calculations of the magnetism of FeOH
Sergey Stolbov, Richard A. Klemm, Talat S. Rahman
By expanding the wave function in plane waves, we use the pseudopotential method of density functional theory within the generalized gradient approximation to calculate the effecti…
First Principles Study of Adsorption, Diffusion and Dissociation of NH_3 on Ni and Pd Surfaces
Sergey Stolbov, Talat S. Rahman
Using the plane wave pseudopotential method within the density functional theory with the generalized gradient approximation for exchange and correlation potential, we have calcula…
Effect of dipolar interactions on the magnetization of a cubic array of nanomagnets
Marisol Alcantara Ortigoza, Richard A. Klemm, Talat S. Rahman
We investigated the effect of intermolecular dipolar interactions on a cubic 3D ensemble of 5X5X4=100 nanomagnets, each with spin . We employed the Landau-Lifshitz-Gilbert e…
