  1. 1. Nanoelectromechanical systems from carbon nanotubes and graphene

    Författare :Niklas Lindahl; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :carbon nanotubes; graphene; nanoelectromechanical systems; fabrication; fabrication;

    Sammanfattning : 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. LÄS MER

  2. 2. Field Emission from Multi-walled Carbon Nanotubes and its Application in Nanoelectromechanical Systems

    Författare :Martin Sveningsson; Chalmers University of Technology; []
    Nyckelord :nanoelectromechanical systems; electron field emission; Fowler-Nordheim theory; Carbon nanotubes; Ohmic heating;

    Sammanfattning : Films of aligned multi-walled carbon nanotubes (MWCNTs) areinteresting for applications such as cold emission cathodes in flat-panel display technology and in lighting elements. MWCNTs are, besides this, good candidates to be used innanoelectromechanical systems (NEMS). LÄS MER

  5. 5. Integration and Fabrication Techniques for 3D Micro- and Nanodevices

    Författare :Andreas C. Fischer; Frank Niklaus; Karl F. Böhringer; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
