2. 1. Microwave characterisation of electrodes and field effect transistors based on graphene

   Author : MICHAEL ANDERSSON; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; graphene electrodes; microwave amplifiers; noise measurements; microwave FETs; CVD graphene; noise modelling; FBARs.; nanofabrication; subharmonic resistive mixers; small-signal FET modelling;

   Abstract : The isolation of the two-dimensional material graphene, a single hexagonal sheet of carbon atoms, is believed to trigger a revolution in electronics. Theory predicts unprecedented carrier velocities in ideal graphene, from which ultrahigh speed graphene field effect transistors (GFETs) are envisioned. READ MORE

   Abstract : Graphene is a two-dimensional sheet of carbon atoms with numerous envisaged applications owing to its exciting properties. In particular, ultrahigh-speed graphene field effect transistors (GFETs) are possible due to the unprecedented carrier velocities in ideal graphene. READ MORE

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

   Author : Omid Habibpour; Chalmers tekniska högskola; []
   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.

   Abstract : Graphene is a one-atom-thick sheet of carbon with numerous impressive properties. It is a promising material for future high-speed nanoelectronics due to its intrinsic superior carrier mobility and very high saturation velocity. READ MORE

7. 5. Computational Studies of Graphene Growth and Carbonaceous Polyethylene Nanocomposites

   Author : Shayesteh Haghighatpanah; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Nanotubes; Polyethylene; Molecular Modelling.; Graphene;

   Abstract : Graphene, the youngest allotrope of carbon, has attracted a lot of attention in different fields of science due to its unique electrical, mechanical, and optical properties. Controlling the growth of graphene is a very topical subject and critical for producing material with desired properties since the properties of graphene are highly dependent on its atomic structure and it is often desirable that the material contains very few or (if possible) no defects.
