The lattice energy includes at least nearest and next-to-nearest neighbour interactions: the latter have the role of penalising changes of orientation. In the heterogeneous case, we obtain an estimate on the minimal energy spent to match different equilibria. This gives insight into the nucleation of dislocations in epitaxially grown heterostructured nanowires.enNonlinear elasticityDiscrete to continuumGeometric rigidityNext-to-nearest neighboursGamma-convergenceDimension reductionHeterostructuresDislocationsPreprint
