Electron Coherence

In narrow channels the properties of the sidewalls can have a crucial effect on both the physics and any device functionality of the electronic transport through these structures. We assess the use of electron beam and "dry etching" fabrication techniques to define sidewalls by studying the influence of the sidewalls on the quantum transmission through the channels and, in particular, show the sidewall scattering to be inelastic in nature and to have implications ranging from electron heating to electron coherence effects.

AbstractThis article studies quantum interference effects and their influence on the electronic transport through a parallel triple quantum-dot system coupled to normal and superconducting leads in the linear response and non-equilibrium regime. We model the system by a triple impurity Anderson Hamiltonian including the Coulomb intra-dot correlations in all quantum-dots. Using the non-equilibrium Green’s function formalism, we calculate the Andreev conductance and the transmittance for energies within the superconductor gap. Our results show that the Andreev reflection spectra, both in the presence and absence of Coulomb interaction, reveal Fano and Dicke-like resonances in analogy to the Fano and Dicke effects in atomic physics. As one of the main results, we obtain that the charge shows abrupt changes due to the Dicke effect.
