Cascade morphology transition in bcc metals
Wahyu Setyawan, Aaron P. Selby, Niklas Juslin +3
Energetic atom collisions in solids induce shockwaves with complex morphologies. In this paper, we establish the existence of a morphological transition in such cascades. The order…
The role of stoichiometric vacancy periodicity in pressure-induced amorphization of the Ga2SeTe2 semiconductor alloy
Najeb Abdul-Jabbar, Bora Kalkan, Alastair MacDowell +3
We observe that pressure-induced amorphization of Ga2SeTe2 (a III-VI semiconductor) is directly influenced by the periodicity of its intrinsic defect structures. Specimens with per…
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…
Displacement cascades and defects annealing in tungsten, Part II: Object kinetic Monte Carlo Simulation of Tungsten Cascade Aging
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…
