Coherent electron transport in quasi one-dimensional carbon-based systems
This Colloquium discusses the coherent electron transport properties of non-ideal quasi-onedimensional carbon-based systems, i.e. graphene nanoribbons, carbon nanotubes and linear chains. Results are based on numerical simulations that implement Schröedinger/Poisson as well as non-equilibrium polaronic methodologies for the calculation of quantities relative to the conduction. Attention is paid...
متن کاملUnusual spectral behavior of charge-density waves with imperfect nesting in a quasi-one-dimensional metal.
Low-temperature electronic properties of the charge-density-wave system NbSe3 are reported from angle-resolved photoemission at 15 K. The effect of two instabilities q(1) and q(2) on the k-resolved spectral function is observed for the first time. With a pseudogap background, the gap spectra exhibit maxima at Delta*(1) approximately 110 meV and Delta*(2) approximately 45 meV. Imperfectly nested...
متن کاملCalculation of Quasi-one-dimensional Interacting Electron Gas Using the Hartree-Fock Method
In this paper, the Hartree-Fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. The bare coulomb interaction between electrons has been assumed. For this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...
متن کاملAnomalous Diffusion in Quasi One Dimensional Systems
In order to perform quantum Hamiltonian dynamics minimizing localization effects, we introduce a quasi-one dimensional tight-binding model whose mean free path is smaller than the size of the sample. This size, in turn, is smaller than the localization length. We study the return probability to the starting layer using direct diagonalization of the Hamiltonian. We create a one dimensional excit...
متن کاملHitchhiking transport in quasi-one-dimensional systems
– In the conventional theory of hopping transport the positions of localized electronic states are assumed to be fixed, and thermal fluctuations of atoms enter the theory only through the notion of phonons. On the other hand, in 1D and 2D lattices, where fluctuations prevent formation of long-range order, the motion of atoms has the character of the large scale diffusion. In this case the pictu...
