Abstract

Dislocation accommodation mechanisms in monolayer and bilayer graphene.

I will begin with a brief account of the computational methodology used in calculations. We divide calculations into two steps: a first harmonic step aimed at building a pattern of defects into the lattice followed by a fully-nonlinear relaxation. Then, I will evaluate a number of dislocation dipole and quadrupole configurations in monolayer and bilayer graphene and document different accommodation mechanisms.
