“…The resulting second-quantized effective low-energy theory of a graphite sheet is given by the 2D massless Dirac Hamiltonian [40], 4) in accordance with the spectrum (2.1). Here τ = (τ x , τ y ) are standard Pauli matrices.…”

We derive the effective low-energy theory for single-wall carbon nanotubes including the Coulomb interactions among electrons. The generic model found here consists of two spin-1 2 fermion chains which are coupled by the interaction. We analyze the theory using bosonization, renormalization-group techniques, and Majorana refermionization. Several experimentally relevant consequences of the breakdown of Fermi liquid theory observed here are discussed in detail, e.g., magnetic instabilities, anomalous conductance laws, and impurity screening profiles.

“…Depending on helicity and diameter, these 1D nanostructures may be metals or semiconductors. 29,[60][61][62] The electronic structure of the SWNTs is related to a 2D graphene sheet, but, because of the radial confinement of the wave function, the continuous electronic density of states (DOS) in graphite divides into a series of spikes in SWNTs which are referred to as Van Hove singularities. Electronic transitions between these singularities give rise to prominent features in scanning tunneling spectroscopy (STS) 22,23 and transmission spectroscopy.…”

In this Account we highlight the experimental evidence in favor of our view that carbon nanotubes should be considered as a new macromolecular form of carbon with unique properties and with great potential for practical applications. We show that carbon nanotubes may take on properties that are normally associated with molecular species, such as solubility in organic solvents, solutionbased chemical transformations, chromatography, and spectroscopy. It is already clear that the nascent field of nanotube chemistry will rival that of the fullerenes.

“…Carbon nanotubes [1][2][3][4] ͑CNTs͒ are arguably the best available material for realizing nano-and molecular-scale electronics and sensor devices. [5][6][7] The feasibility of single-walled carbon nanotube-͑SWNT͒ based electronic devices, such as interconnects 8,9 in molecular electronics, junction rectifiers, [9][10][11] field-effect transistors ͑FETs͒, 12,13 and logic gates, 14 has been demonstrated in recent experiments.…”

High-throughput field-effect transistors ͑FETs͒ containing over 300 disentangled, high-purity chemical-vapor-deposition-grown single-walled carbon nanotube ͑SWNT͒ channels have been fabricated in a three-step process that creates more than 160 individually addressable devices on a single silicon chip. This scheme gives a 96% device yield with output currents averaging 5.4 mA and reaching up to 17 mA at a 300 mV bias. Entirely semiconducting FETs are easily realized by a high current selective destruction of metallic tubes. The excellent dispersity and nearly-defect-free quality of the SWNT channels make these devices also useful for nanoscale chemical and biological sensor applications.
