We describe the synthesis of bilayer graphene thin films deposited on insulating silicon carbide and report the characterization of their electronic band structure using angle-resolved photoemission. By selectively adjusting the carrier concentration in each layer, changes in the Coulomb potential led to control of the gap between valence and conduction bands. This control over the band structure suggests the potential application of bilayer graphene to switching functions in atomic-scale… 

Tunable band gap in hydrogenated bilayer graphene.

The electronic structural characteristics of hydrogenated bilayer graphene under a perpendicular electric bias using first-principles density functional calculations shows a ferromagnetic semiconductor with a tunable band gap with implications for future graphene-based device applications.

Atomic hole doping of graphene.

It is shown by angle-resolved photoemission spectroscopy that substantial hole doping in the conical band structure of epitaxial graphene monolayers can be achieved by the adsorption of bismuth, antimony, or gold.

Single-layer graphene with electronic properties of a gated bilayer

We demonstrate that single layer graphene exhibits the electronic structure of a bilayer when it is connected to two gated bilayers. The energy gap characteristic for gated bilayer is induced in the

Electron-state tuning of multilayer graphene by defects

Electronic band structures of graphene thin films, in which the topmost layer possesses atomic and topological defects, are studied using the density functional theory. Our calculations showed that

Electronic transport properties of top-gated monolayer and bilayer graphene devices on SiC

We studied the electronic transport properties of monolayer and bilayer graphene in top-gated geometries. Monolayer and bilayer graphene were epitaxially grown by thermal decomposition of SiC. The

In this thesis we investigate the fundamental properties of electronic transport in bilayer graphene. We do this by confining electrons to narrow constrictions and small islands. Our key result is

In this work, we have investigated the spectral function of graphene on a monolayer of intercalated gold on Ru(0001) using angle-resolved photoemission spectroscopy (ARPES). The intercalation leads

Dirac Particles in Epitaxial Graphene Films Grown on SiC

We report on the transport and structural properties of graphene layers grown epitaxially on hexagonal SiC. Experimentally, the charge carriers in epitaxial graphene are found to be chiral and the

Electron Transmission through Graphene Bilayer Flakes

We investigate the electronic transport properties of a bilayer graphene ake contacted by two monolayer nanoribbons. This nite-size bilayer ake can be built by overlapping two semi-in nite ribbons.

Electronic Properties of Multilayer Graphene

In this chapter, we study the electronic structure of arbitrarily stacked multilayer graphene in the absence or presence of magnetic field. The energy band structure and the Landau-level spectrum are



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.

Fabrication and electric-field-dependent transport measurements of mesoscopic graphite devices

We have developed a unique micromechanical method to extract extremely thin graphite samples. Graphite crystallites with thicknesses ranging from 10 to 100nm and lateral size ∼2μm are extracted from

Quasiparticle band structure of bulk hexagonal boron nitride and related systems.

It is shown that the equivalent of the interlayer state in the case of the isolated boron nitride sheet plays the same role as in the bulk case in determing the band gap.


When annealed at elevated temperatures under vacuum, silicon carbide surfaces show a tendency towards graphitization. Using the sensitivity of empty conduction-band states dispersion towards the

We derive an effective two-dimensional Hamiltonian to describe the low-energy electronic excitations of a graphite bilayer, which correspond to chiral quasiparticles with a parabolic dispersion

Experimental observation of the quantum Hall effect and Berry's phase in graphene

An experimental investigation of magneto-transport in a high-mobility single layer of graphene observes an unusual half-integer quantum Hall effect for both electron and hole carriers in graphene.

High-field electrical transport in single-wall carbon nanotubes

The intrinsic high-field transport properties of metallic single-wall carbon nanotubes are measured using low-resistance electrical contacts and it is shown that the current-voltage characteristics can be explained by considering optical or zone-boundary phonon emission as the dominant scattering mechanism at high field.

The Band Theory of Graphite
