Abstract: “Nanoelectromechanical systems” (NEMS) are nanometer-sized mechanical structures coupled to electronic devices of comparable size. The coupling between mechanical and electronic degrees of freedom, combined with their mesoscopic size, provide these systemswith some unique properties that make them interesting from both the fundamental and technological point of view. In this thesis, we present theoretical work about a specific kind of NEMS, that is a suspended doubly clamped carbon nanotube in... more
