Abstract: Over the last two decades nanotechnology has been a very active field of scientific research, both from fundamental perspectives as well as for applications in technology and consumer goods. In this thesis, theoretical work on quantum mechanical effects on charge transport in nanoelectromechanical systems is presented. In particular, the effects of electron-vibron interactions in suspended nanowire structures are analysed and discussed. The thesis is structured around the appended scientific ... more
