  2. 1. Carbon-nanotube-based nanoelectromechanics

    Author : Magnus Jonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electromechanical instabilities; multi-mode excitations; NEMS; suspended carbonnanotubes; Nanoelectromechanicalsystems; non-linearresonances; nanorelay; carbon nanotubes; surface forces;

    Abstract : 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. READ MORE

  4. 2. Electromechanical Interactions in Shuttle Systems and Carbon Nanotube Relays

    Author : Tomas Nord; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coulomb blockade; carbon nanotubes; memory device; nanorelay; single electron tunneling; van der Waals forces; NEMS; shuttle transport; mesoscopic; nanoelectromechanical systems;

    Abstract : In this thesis we theoretically investigate two kinds of nanoscale systems where there is a strong electromechanical coupling, i.e. an intricate relation between the Coulomb forces that can appear in these systems and the displacements of parts of the systems that they cause.

  5. 3. Modeling a carbon-nanotube-based nanoelectromechanical relay

    Author : Magnus Jonsson; Chalmers tekniska högskola; []
    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

  6. 4. Fabrication and Characterisation of Carbon Nanotube Array Thermal Interface Materials

    Author : ANDREAS NYLANDER; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; reliability test; thermal management; thermal interface material; chemical functionalization;

    Abstract : The performance of electronic devices has long been limited by thermal dissipation which will result in device failure if not handled properly. The next generation of integrated circuit (IC) devices will feature new packaging technologies like heterogeneous integration as well as 3D stacking which entails additional emphasis on the thermal management solutions employed.

  7. 5. Self-assembly Strategies for Functional DNA Nanostructures

    Author : John Tumpane; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon nanotube; polarised spectroscopy; nanotechnology; self-assembly; orientation; lipid membrane; gel electrophoresis; DNA;

    Abstract : The technological revolution of the twentieth century was famously subject to Moore’s law which related the rate of growth to the ability to scale-down the size of the components – size matters. Several decades later we are, however, approaching the limit of what is possible with silicon wafers. READ MORE
