Description
In this talk I will discuss models for analyzing inter-crystalline
boundaries that arise from differences in atomic spacing. In the case of
semi-coherent interfaces, where the misfit between crystal lattices is small, the interfaces can be resolved into sequences of edge dislocations,
leading to an interfacial energy that exhibits Read–Shockley-type superlinear scaling as a function of the misfit.
