The Goos-Hänchen (GH) effect is an interference effect on total internal reflection at an interface, resulting in a shift sigma of the reflected beam along the interface. We show that the GH effect at a p-n interface in graphene depends on the pseudospin (sublattice) degree of freedom of the massless Dirac fermions, and find a sign change of sigma at angle of incidence alpha=arcsin sqrt[sinalpha{c}] determined by the critical angle alpha{c} for total reflection. In an n-doped channel with p…

Goos-Hänchen-like shifts for Dirac fermions in monolayer graphene barrier
Abstract. The quantum Goos-Hänchen effect in graphene is found to be the lateral shift of Dirac fermions on the total reflection at a single p-n interface. In this paper, we investigate the lateral
Sticky Goos-Hanchen effect at normal/superconductor interface
We study the quantum Goos-Hanchen (GH) effect for wave-packet dynamics at a normal/superconductor (NS) interface. We find that the effect is amplified by a factor , with EF the Fermi energy and Δ the

It is suggested that the CGD and its GH component can be electrostatically measured by the conductance difference in a spin precession experiment under weak magnetic fields, and it is indicated that it is a generally nonzero self-interference delay that relates the IGD to the dwell time in graphene.
Goos-Hänchen-like shifts at a metal/superconductor interface
At a normal-metal/superconductor interface, an incident electron from the normal-metal (N) side can be normally reflected as an electron or Andreev reflected as a hole. We show that pronounced
Photon-assisted Spectroscopy of Dirac Electrons in Graphene
The quantum Goos-Hanchen effect in graphene is investigated. The Goos-Hanchen phase shift is derived by solving the Dirac eigenvalue differential equation. This phase shift varies with the angle of
Giant Goos-Hänchen shift in graphene double-barrier structures
We report giant Goos-Hanchen shifts [Goos and Hanchen, Ann. Phys. 436, 333 (1947)] for electron beams tunneling through graphene double barrier structures. We find that inside the transmission gap

Colloquium: Andreev reflection and Klein tunneling in graphene
A colloquium-style introduction to two electronic processes in a carbon monolayer (graphene) is presented, each having an analog in relativistic quantum mechanics. Both processes couple electronlike
Calculation of the conductance of a graphene sheet using the Chalker-Coddington network model
The Chalker-Coddington network model (introduced originally as a model for percolation in the quantum Hall effect) is known to map onto the two-dimensional Dirac equation. Here we show how the
The Focusing of Electron Flow and a Veselago Lens in Graphene p-n Junctions
The focusing of electric current by a single p-n junction in graphene is theoretically predicted and may be useful for the engineering of electronic lenses and focused beam splitters using gate-controlled n-p-n junctions in graphene-based transistors.
The electronic properties of graphene
Graphene is the first example of truly two‐dimensional crystals – it's just one layer of carbon atoms. It turns out that graphene is a gapless semiconductor with unique electronic properties

We investigate the lateral displacements for ballistic electron beams in a two-dimensional electron gas modulated by metallic ferromagnetic (FM) stripes with parallel and antiparallel (AP)
‘Trapped rainbow’ storage of light in metamaterials
It is demonstrated theoretically that an axially varying heterostructure with a metamaterial core of negative refractive index can be used to efficiently and coherently bring light to a complete standstill, and allows for high in-coupling efficiencies and broadband, room-temperature operation.
Electric Field Effect in Atomically Thin Carbon Films
Monocrystalline graphitic films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands and they exhibit a strong ambipolar electric field effect.

Although light propagation in weakly modulated photonic crystals is basically similar to propagation in a diffraction grating in which conventional refractive index loses its meaning, we demonstrate
