Atomistic investigations of misfit dislocation for Pt/SiC(111) interface fracture

摘要

An interface has some special features in a fracture because of its misfit dislocations. In this work, we use ab initio-based interatomic potentials to study this problem in a Pt/SiC(1 1 1) interface. The whole dynamic process is simulated in the atomistic scale. Micro-cracks and jump points are found in the fracture, which lead to some interesting results.
