Probing the Structure and Energetics of Dislocation Cores in SiGe Alloys through Monte Carlo Simulations
Ioannis N. Remediakis, David E. Jesson, Pantelis C. Kelires
We present a methodology for the investigation of dislocation energetics in segregated alloys based on Monte Carlo simulations which equilibrate the topology and composition of the…
