Floquet spectrum and transport through an irradiated graphene ribbon.

Graphene subject to a spatially uniform, circularly polarized electric field supports a Floquet spectrum with properties akin to those of a topological insulator. The transport properties of this system, however, are complicated by the nonequilibrium occupations of the Floquet states. We address this by considering transport in a two-terminal ribbon geometry for which the leads have well-define...

Graphene Optoelectronics based on Antidot Superlattices

Graphene is well known for its outstanding electronic, thermal, and mechanical properties, and has recently gained tremendous interest as a nanomaterial for optoelectronic devices. We review our recent efforts on exfoliated graphene with a particular focus on the influence of graphene’s chiral edges on the electronic and optical properties. We first show that Raman spectroscopy can not only be ...
