This article reviews the basic theoretical properties of graphene, a\ntwodimensional allotrope of carbon, with unusual electronic properties. The\nelementary excitations are linearly dispersing Dirac fermions with vanishing\nelectronic density of…

Surface plasmons are waves that propagate along the surface of a conductor. By altering the structure of a metal's surface, the properties of surface plasmonsin particular their interaction with lightcan be tailored, which offers the potential…

Quantum electrodynamics (resulting from the merger of quantum mechanics and relativity theory) has provided a clear understanding of phenomena ranging from particle physics to cosmology and from astrophysics to quantum chemistry. The ideas…

Certain insulators have exotic metallic states on their surfaces. These states are formed by topological effects that also render the electrons travelling on such surfaces insensitive to scattering by impurities. Such topological insulators may…

Choosing good problems is essential for being a good scientist. But what is a good problem, and how do you choose one? The subject is not usually discussed explicitly within our profession. Scientists are expected to be smart enough to figure it out…

Graphene is the twodimensional building block for carbon allotropes of every other dimensionality. We show that its electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers. The D peak second order…

From a theory of Hohenberg and Kohn, approximation methods for treating an inhomogeneous system of interacting electrons are developed. These methods are exact for systems of slowly varying or high density. For the ground state, they lead to…

The emerging field of plasmonics has yielded methods for guiding and localizing light at the nanoscale, well below the scale of the wavelength of light in free space. Now plasmonics researchers are turning their attention to photovoltaics, where…

Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator, but have protected conducting states on their edge or surface. The 2D topological insulator is a quantum spin Hall insulator, which is a close…

Insights into conducting research and the writing of scientific papers are given by Prof. Whitesides in this short essay. The manuscript and its guidelines has been circulated within the Whitesides' research group since 1989.

Problems associated with largescale pattern growth of graphene constitute one of the main obstacles to using this material in device applications. Recently, macroscopicscale graphene films were prepared by twodimensional assembly of graphene…

We propose a new implementation of a universal set of one and twoqubit gates for quantum computation using the spin states of coupled singleelectron quantum dots. Desired operations are effected by the gating of the tunneling barrier between…

We study the effects of spin orbit interactions on the low energy electronic structure of a single plane of graphene. We find that in an experimentally accessible low temperature regime the symmetry allowed spin orbit potential converts graphene…

Heightheight correlations for selfaffine surfaces with finite horizontal cutoffs are generally modeled by exponential forms. Three mathematically acceptable, alternate forms for the heightheight correlation function are investigated, to explore…

We describe monocrystalline graphitic films, which are a few atoms thick but are nonetheless stable under ambient conditions, metallic, and of remarkably high quality. The films are found to be a twodimensional semimetal with a tiny overlap between…

Generalized gradient approximations (GGA's) for the exchangecorrelation energy improve upon the local spin density (LSD) description of atoms, molecules, and solids. We present a simple derivation of a simple GGA, in which all parameters (other…

The optical constants n and k were obtained for the noble metals (copper, silver, and gold) from reflection and transmission measurements on vacuumevaporated thin films at room temperature, in the spectral range 0.56.5 eV. The filmthickness range…
