  1. 1. Interaction between electronic and vibrational edge states in graphene

    Författare :Anton Vikström; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; collective excitations; quantum acous- tics; quantum Hall effect; edge waves; graphene; solitons;

    Sammanfattning : A sheet of graphene in a magnetic field perpendicular to the sheet has electronic edge states with nonzero velocities. These edge states are localized to the edge of the sheet on the order of the magnetic length. LÄS MER

  2. 2. Nanomechanical Phenomena in Low-Dimensional Structures

    Författare :Anton Vikström; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superconductivity; acoustic sensors; heat flow; NEMS; surface acoustic waves; solitons; viscoelasticity; electronic edge states;

    Sammanfattning : This is a compilation thesis which investigates various mechanical phenomena in different low-dimensional nanoscale systems. In the first part, we consider a purely mechanical phenomenon: the sensitivity of the dispersion of a Love-type surface acoustic wave (SAW) to geometry and material parameters. LÄS MER
