Giuliano Lazzaroni (University of Wuerzburg): Dislocations in nanowire heterostructures: from discrete to continuum
Wednesday, 17.07.2013 15:00 im Raum N1
We discuss an atomistic model for heterogeneous nanowires, allowing for
dislocations at the interface. We study the limit as the atomic distance
converges to zero, considering simultaneously a dimension reduction and the
passage from discrete to continuum. Employing the notion of Gamma-convergence,
we establish the minimal energies associated to defect-free configurations and
configurations with dislocations at the interface, respectively. It turns out
that dislocations are favoured if the thickness of the wire is sufficiently
large.
