Query: Graphene antidot lattice waveguides   We introduce graphene antidot lattice waveguides: nanostructured graphene
where a region of pristine graphene is sandwiched between regions of graphene
antidot lattices. The band gap in the surrounding antidot lattices enable
localized states to emerge in the central waveguide region. We model the
waveguides via a position-dependent mass term in the Dirac approximation of
graphene, and arrive at analytical results for the dispersion relation and
spinor eigenstates of the localized waveguide modes. To include atomistic
details we also use a tight-binding model, which is in excellent agreement with
the analytical results. The waveguides resemble graphene nanoribbons, but
without the particular properties of ribbons that emerge due to the details of
the edge. We show that electrons can be guided through kinks without additional
resistance and that transport through the waveguides is robust against
structural disorder.
