  1. 1. Bow-tie antenna-coupled graphene FETs for direct detection at 0.6THz

    University essay from Chalmers tekniska högskola/Institutionen för mikroteknologi och nanovetenskap

    Author : Audrey Zak; [2014]
    Keywords : graphene; CVD graphene; terahertz; direct detection; GFET; bow-tie antenna;

    Abstract : The recent demonstration of the electric field effect in graphene, a two-dimensional carbon lattice, and the measurement of its extraordinary room-temperature properties have sparked enormous interest in graphene as a material in electronics. Atomically thin and conductive, graphene has many options for integration with existing electronic devices and opportunities for the development of new devices. READ MORE

  2. 2. Noise Parameter Characterisation of Graphene Field Effect Transistors in the 2-8 GHz Frequency Range

    University essay from Chalmers tekniska högskola/Institutionen för mikroteknologi och nanovetenskap

    Author : Mehbuba Tanzid; [2013]
    Keywords : ;

    Abstract : Graphene is promising for being used as a channel material in high frequency and low noise field effect transistors (FETs). This is facilitated by its superior near-room temperature mobility (10^5 cm^2/V-s) for both type of carriers and predicted high value of saturation velocity (4*10^7 cm/s). READ MORE

  3. 3. Noise Characterisation of Graphene FETs

    University essay from Chalmers tekniska högskola/Institutionen för mikroteknologi och nanovetenskap

    Author : Michael Andersson; [2012]
    Keywords : Graphene FETs; microwave amplifiers; noise measurements; noise figure; subharmonic resistive mixer;

    Abstract : This thesis deals with the first noise performance study of graphene field effect transistors (G-FETs) at microwave frequencies. It considers G-FETs in two different applications, as a subharmonic resistive mixer and in an amplifier. The work encompasses cleanroom fabrication, as well as characterisation by measurement and modelling. READ MORE

  4. 4. Fabrication and Characterization of Graphene Field Effect Transistors

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Sam Vaziri; [2011]
    Keywords : ;

    Abstract : Exceptional electronic properties of graphene have attracted the attention of solid-state physicists and more recently device engineers. From electronic device point of view, graphene is a promising material for future smaller and faster electronics, and it demands extensive amount of research. READ MORE
