  1. 1. Carbon-nanotube-based nanoelectromechanics

    Författare :Magnus Jonsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electromechanical instabilities; multi-mode excitations; NEMS; suspended carbonnanotubes; Nanoelectromechanicalsystems; non-linearresonances; nanorelay; carbon nanotubes; surface forces;

    Sammanfattning : Carbon nanotubes, a novel material with extraordinary mechanical and electrical properties, are good candidates for designing nanoelectromechanical systems. The typical length scale of these systems is nanometers and an important characteristic is a coupling between electrical and mechanical degrees of freedom. LÄS MER

  2. 2. Quantum mechanical effects on charge transport in two mesoscopic systems

    Författare :Gustav Sonne; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoelectromechanical systems; NEMS; carbon nanotubes; carbon peapods; excess current; superconducting weak links; suspended carbon nanotubes; non-linear resonances;

    Sammanfattning : Carbon nanotubes are one of the most promising building blocks for the developing field of nanoelectromechanics. Due to their unique electronic and mechanical properties, these all-carbon systems have been suggested for a range of applications where one wishes to utilse the coupling between mechanical and electronic degrees of freedom on the nanometer length scale.

  3. 3. Shuttle Transport of Charge in Normal and Superconducting Nanostructures

    Författare :Andreas Isacsson; Chalmers University of Technology; []
    Nyckelord :Josephson effect; superconductivity; nanoelectromechanics NEMS ; single electron tunneling; coulomb blockade;

    Sammanfattning : In nanoscale systems, accumulation of charge is associated with large charging energies. If the forces arising due to the Coulomb interaction are comparable to the rigidity of the structures mechanical deformations can couple to the electronic degrees of freedom. LÄS MER
