Object Kinetic Monte Carlo Simulations of Radiation Damage in Bulk Tungsten Part-II: With a PKA Spectrum Corresponding to 14-MeV Neutrons
Giridhar Nandipati, Wahyu Setyawan, Howard L. Heinisch +3
Object kinetic Monte Carlo was employed to study the effect of dose rate on the evolution of vacancy microstructure in polycrystalline tungsten under neutron bombardment. The evolu…
Self-Learning Kinetic Monte Carlo Simulations of Al Diffusion in Mg
Giridhar Nandipati, Niranjan Govind, Amity Andersen +1
Vacancy-mediated diffusion of an Al atom in pure Mg matrix is studied using the atomistic, on-lattice self-learning kinetic Monte Carlo (SLKMC) method. Activation barriers for vaca…
Object Kinetic Monte Carlo Simulations of Radiation Damage in Neutron-Irradiated Tungsten Part-I: Neutron Flux with a PKA Spectrum Corresponding to the High-flux Isotope Reactor
Giridhar Nandipati, Wahyu Setyawana, Howard L. Heinisch +3
Object kinetic Monte Carlo simulations were performed to study the impact of varying dose rate and grain size up to a dose of 1.0 dpa in pure, polycrystalline tungsten, subjected t…
Self-learning kinetic Monte Carlo Simulations of Self-diffusion of small Ag clusters on Ag (111) surface
Syed Islamuddin Shah, Giridhar Nandipati, Talat S. Rahman
The self-diffusion of two-dimensional small Ag islands (containing up to atoms) on Ag(111) surface has been studied using and self-learning kinetic Monte Carlo [J. Phys.: Cond…
Displacement cascades and defects annealing in tungsten, Part I: defect database from molecular dynamics simulations
Wahyu Setyawan, Giridhar Nandipati, Kenneth J. Roche +3
Molecular dynamics simulations have been used to generate a comprehensive database of surviving defects due to displacement cascades in bulk tungsten. Twenty one data points of pri…

Giridhar Nandipati, Wahyu Setyawan, Howard L. Heinisch +3
We describe the results of object kinetic Monte Carlo (OKMC) simulations of the annealing of primary cascade damage in bulk tungsten using a comprehensive database of cascades obta…
Island Size Selectivity and island-shape analysis during 2D Island Coarsening of Ag/Ag (111) Surface
Giridhar Nandipati, Abdelkader Kara, Syed Islamuddin Shah +1
In our earlier study of Ag island coarsening on Ag(111) surface using kinetic Monte Carlo (KMC) simulations we found that during early stages coarsening proceeds as a sequence of s…
