    Abstract : Vibration control requires high dynamic stiffness in mechanical structures for a reliable performance under extreme conditions. Dynamic stiffness composes the parameters of stiffness (K) and damping (η) that are usually in a trade-off relationship. This thesis study aims to break the trade-off relationship. 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.
