    Abstract : The past few decades have seen an explosive increase ininformation transfer, fuelled by the enormous growth of theInternet, telecommunication applications, and mass mediasystems in general. Because of the very high bandwidthpotential promised by optical fibre communication technology,the area of all-optical networking has received a great amountof attention. READ MORE

  2. 2. Carbon-nanofibre-based tunable photonic crystals

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Robert Rehammar; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transfer matrix; carbon nanofibre; fdtd; Photonic crystal; PECVD; plane wave expansion; tunable;

    Abstract : Photonic crystals are materials with periodically varying refractive indices. In conventional photonic crystal design it is hard to achieve tunable structures in the visible range. That is, structures with changeable optical properties. READ MORE

    Abstract : 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). READ MORE

  5. 5. Fabrication, Characterisation and Modelling of Subharmonic Graphene FET Mixers

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Omid Habibpour; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gate dielectric; Graphene; harmonic balance analysis.; subharmonic resistive mixers; microwave FETs; device modelling;

    Abstract : Graphene has exceptional carrier transport properties which makes it a promising material for future nanoelectronics. The high carrier mobility along with the ability to switch between n- and p-channel in a graphene field effect transistor (G-FET) truly distinguishes it from other types of FET technologies and enables completely new high frequency devices.
