[Influence des effets magnéto-élastique et polaronique sur le transport électronique à travers un point quantique formé avec un nanotube de carbone suspendu]
Nous étudions le transport électronique à travers un point quantique formé avec un nanotube de carbone suspendu. En présence dʼun champ magnétique perpendiculaire au nanotube et dʼune grille métallique, deux forces agissent sur les électrons : la force de Laplace et la force électrostatique. Elles induisent toutes les deux un couplage entre les électrons et les modes dʼoscillations mécaniques transverses. Nous trouvons quʼune différence entre les deux mécanismes de couplage se manifeste à des ordres supérieurs dans le courant tunnel.
We investigate the electronic transport through a suspended carbon-nanotube quantum dot. In the presence of a magnetic field perpendicular to the nanotube and a nearby metallic gate, two forces act on the electrons: the Laplace and the electrostatic force. They both induce coupling between the electrons and the mechanical transverse oscillation modes. We find that the difference between the two mechanisms appears in the cotunneling current.
