  1. 1. Nanoelectromechanical systems from carbon nanotubes and graphene

    University dissertation from Göteborg : University of Gothenburg

    Author : Niklas Lindahl; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon nanotubes; graphene; nanoelectromechanical systems; fabrication;

    Abstract : Carbon nanotubes and graphene have many interesting properties. To exploit the properties in applications their synthesis and incorporation in devices has to be understood and controlled. This thesis is based on experimental studies on synthesis of carbon nanotubes and fabrication of nanoelectromechanical systems from carbon nanotubes and graphene. READ MORE

  2. 2. Modeling a carbon-nanotube-based nanoelectromechanical relay

    University dissertation from Göteborg : University of Gothenburg

    Author : Magnus Jonsson; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surface forces; NEMS; carbon nanotubes; dissipation; nanorelay; mechanical resonances; stiction; high frequency applications; Nanoelectromechanical systems; field emission; tunable resonances;

    Abstract : We have theoretically investigated the properties of a three-terminal carbon-nanotube-based nanoelectromechanical relay. The system operationis based on an coupling between electrical and mechanical degrees of freedom which is a typical characteristic of a NEMS device. READ MORE

  3. 3. Modelling of Molecular-Scale Nanoelectromechanical Systems

    University dissertation from Göteborg : University of Gothenburg

    Author : Caroline Huldt; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; shuttle; mesoscopic; NEMS; graphene; multiscale; DFTB; DFT;

    Abstract : Nanoelectromechanical systems (NEMS) couple electronic and mechanical degrees of freedom in a nanoscopic structure. The small size introduces many atomistic and quantum mechanical features which on the one hand open up for interesting new features and possibilities but on the other hand make it very difficult to formulate quantitative predictions.

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Andreas C. Fischer; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microelectromechanical systems; MEMS; Nanoelectromechanical systems; NEMS; silicon; wafer-level; chip-level; through silicon via; TSV; packaging; 3D packaging; vacuum packaging; liquid encapsulation; integration; heterogeneous integration; wafer bonding; microactuators; shape memory alloy; SMA; wire bonding; magnetic assembly; self-assembly; 3D; 3D printing; focused ion beam; FIB;

    Abstract : The development of micro and nano-electromechanical systems (MEMS and NEMS) with entirely new or improved functionalities is typically based on novel or improved designs, materials and fabrication methods. However, today’s micro- and nano-fabrication is restrained by manufacturing paradigms that have been established by the integrated circuit (IC) industry over the past few decades. READ MORE

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

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Gustav Sonne; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoelectromechanical systems; NEMS; carbon nanotubes; carbon peapods; excess current; superconducting weak links; suspended carbon nanotubes; non-linear resonances;

    Abstract : 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.
