Electronic properties of graphene antidot lattices (2009)
Fuerst, Joachim A., Pedersen, Jesper G., Flindt, Christian, Mortensen, Niels Asger, Brandbyge, Mads, Pedersen, Thomas G., ...
Graphene antidot lattices constitute a novel class of nano-engineered graphene devices with controllable electronic and optical properties. An antidot lattice consists of a periodic array of holes...
DFT study of graphene antidot lattices: The roles of geometry relaxation and spin (2009)
Fuerst, Joachim A., Pedersen, Thomas G., Brandbyge, Mads, Jauho, Antti-Pekka
Graphene sheets with regular perforations, dubbed as antidot lattices, have theoretically been predicted to have a number of interesting properties. Their recent experimental realization with lattice...
Optical properties of graphene antidot lattices (2008)
Pedersen, Thomas G., Flindt, Christian, Pedersen, Jesper, Jauho, Antti-Pekka, Mortensen, Niels Asger, Pedersen, Kjeld
Undoped graphene is semi-metallic and thus not suitable for many electronic and optoelectronic applications requiring gapped semiconductor materials. However, a periodic array of holes (antidot...
Graphene Antidot Lattices - Designed Defects and Spin Qubits (2008)
Pedersen, Thomas G., Flindt, Christian, Pedersen, Jesper, Mortensen, Niels Asger, Jauho, Antti-Pekka, Pedersen, Kjeld
Antidot lattices, defined on a two-dimensional electron gas at a semiconductor heterostructure, are a well-studied class of man-made structures with intriguing physical properties. We point out that...
Optical second harmonic generation from Wannier excitons (2007)
Pedersen, Thomas G., Cornean, Horia D.
Excitonic effects in the linear optical response of semiconductors are well-known and the subject of countless experimental and theoretical studies. For the technologically important second order...
Cornean, Horia D., Pedersen, Thomas G., Ricaud, Benjamin
Recent two-photon photo-luminescence experiments give accurate data for the ground and first excited excitonic energies at different nanotube radii. In this paper we compare the analytic...
The Faraday effect revisited: General theory (2005)
Cornean, Horia D., Nenciu, G., Pedersen, Thomas G.
This paper is the first in a series revisiting the Faraday effect, or more generally, the theory of electronic quantum transport/optical response in bulk media in the presence of a constant magnetic...
