Higher-order Frenkel-Kontorova modelling of crowdions

In this paper we model 〈111〉 self-interstitial defects, or crowdions, using an extended version of the analytical Frenkel-Kontorova model. We use a more general potential than the traditional sinusoidal one, and find that it can better describe the lattice potentials experienced by crowdions in the...
