Thermoelectric Effects in Nanowire-Based MOSFETs

Autor: Bosisio, Riccardo, Fleury, Geneviève, Gorini, Cosimo, Pichard, J. -L

Publikováno v: Advances in Physics: X, 2017, 2, pp.344

We review a series of works describing thermoelectric effects in gated disordered nanowires (field effect transistor device configuration). After considering the elastic coherent regime characterizing sub-Kelvin temperatures, we study the inelastic a

Critical quantum chaos and the one dimensional Harper model

Autor: Evangelou, S. N., Pichard, J. -L.

We study the quasiperiodic Harper's model in order to give further support for a possible universality of the critical spectral statistics. At the mobility edge we numerically obtain a scale-invariant distribution of the bands $S$, which is closely d

Parametric statistics of the scattering matrix: From metallic to insulating quasi-unidimensional disordered systems

Autor: Mucciolo, E. R., Jalabert, R. A., Pichard, J. -L.

We investigate the statistical properties of the scattering matrix $S$ describing the electron transport through quasi-one dimensional disordered systems. For weak disorder (metallic regime), the energy dependence of the phase shifts of $S$ is found

$h/2e$--Oscillations for Correlated Electron Pairs in Disordered Mesoscopic Rings

Autor: Weinmann, D., Mueller-Groeling, A., Pichard, J. -L., Frahm, K.

Publikováno v: Phys. Rev. Lett. 75 1995 1598

The full spectrum of two interacting electrons in a disordered mesoscopic one--dimensional ring threaded by a magnetic flux is calculated numerically. For ring sizes far exceeding the one--particle localization length $L_1$ we find several $h/2e$--pe

Scaling in Interaction-Assisted Coherent Transport

Autor: Frahm, K., Mueller-Groeling, A., Pichard, J. -L., Weinmann, D.

The pair localization length $L_2$ of two interacting electrons in one--dimensional disordered systems is studied numerically. Using two direct approaches, we find $L_2 \propto L_1^{\alpha}$, where $L_1$ is the one-electron localization length and $\

Universal Quantum Signatures of Chaos in Ballistic Transport

Autor: Jalabert, R. A., Pichard, J. -L., Beenakker, C. W. J.

Publikováno v: Europhys.Lett. 27 (1994) 255

The conductance of a ballistic quantum dot (having chaotic classical dynamics and being coupled by ballistic point contacts to two electron reservoirs) is computed on the single assumption that its scattering matrix is a member of Dyson's circular en

Long-Range Energy-Level Interaction in Small Metallic Particles

Autor: Jalabert, R. A., Pichard, J. -L., Beenakker, C. W. J.

Publikováno v: Europhys.Lett.24:1,1993

We consider the energy level statistics of non-interacting electrons which diffuse in a $ d $-dimensional disordered metallic conductor of characteristic Thouless energy $ E_c. $ We assume that the level distribution can be written as the Gibbs distr
