Inkjet-defined field-effect transistors from chemical vapour deposited graphene
DUESBERG, GEORG; NOLAN, HUGO; MCEVOY, NIALL; BERNER, NINA; HALLAM, TOBY (2014)In this work, inkjet printing methods are used to create graphene field effect transistors with mobilities up to 3000 cm2 V?1 s?1. A commercially-available chromium-based ink is used to define the device channel by inhibiting ... -
Nitrogen-doped pyrolytic carbon films as highly electrochemically active electrodes
NOLAN, HUGO; DUESBERG, GEORG; MCEVOY, NIALL (2013)Nitrogen-doped Pyrolytic Carbon (N-PyC) films were employed as an electrode material in electrochemical applications. PyC was grown by via non-catalysed chemical vapour deposition and subsequently functionalised via exposure ... -
Nitrogen-doped reduced graphene oxide electrodes for electrochemical supercapacitors
DUESBERG, GEORG; NOLAN, HUGO; MCEVOY, NIALL; MENDOZA SANCHEZ, BEATRIZ; NICOLOSI, VALERIA (2014)Herein we use Nitrogen-doped reduced Graphene Oxide (N-rGO) as the active material in supercapacitor electrodes. Building on a previous work detailing the synthesis of this material, electrodes were fabricated via ... -
Plasma-assisted simultaneous reduction and nitrogen doping of graphene oxide nanosheets
DUESBERG, GEORG; MCEVOY, NIALL; NOLAN, HUGO; REZVANI, EHSAN (2013)An environmentally benign and scalable route for the production of gram scale quantities of nitrogen-doped graphene using a downstream microwave plasma source is reported. Simultaneous reduction and doping of graphene oxide ... -
Synthesis and Analysis of Thin Conducting Pyrolytic Carbon Films
DUESBERG, GEORG; KUMAR, SHISHIR; REZVANI, EHSAN; NOLAN, HUGO; KEELEY, GARETH; BLAU, WERNER; MCEVOY, NIALL (2012)We report on an adjustable process for chemical vapour deposition of thin films of pyrolytic carbon on inert substrates using an acetylene feedstock. Through modification of the reaction parameters control over film thickness ...
