    • Functionalisation of graphene surfaces with downstream plasma treatments 

      DUESBERG, GEORG STEFAN; NOLAN, HUGO CONOR; MC EVOY, NIALL; HALLAM, TOBY (2013)
      We report on an adjustable process for the functionalisation of graphene surfaces with a downstream plasma source. The parameters of oxygen plasma treatments are modified such that oxygenated functionalities can be added ...

    • High-Performance Sensors Based on Molybdenum Disulfide Thin Films 

      DUESBERG, GEORG; HALLAM, TOBY; MC EVOY, NIALL; GATENSBY, RILEY (2013)
      High-performance sensors based on molybdenum disulfide (MoS2) grown by sulfurization of sputtered molybdenum layers are presented. Using a simple integration scheme, it is found that the electrical conductivity of MoS2 ...

    • Highly sensitive, transparent, and flexible gas sensors based on gold nanoparticle decorated carbon nanotubes 

      DUESBERG, GEORG STEFAN; NOLAN, HUGO CONOR; HALLAM, TOBY (2013)
      We report on a high performance flexible and transparent chemical sensor based on functionalised single-walled carbon nanotubes (SWCNTs). The SWCNT films were spray-deposited on transparent and flexible plastic substrates, ...

    • 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 ...

    • Origami-based spintronics in graphene 

      DUESBERG, GEORG; HALLAM, TOBY; FERREIRA, MAURO (2013)
      We show that periodically folded graphene sheets with enhanced spin-orbit interaction due to curvature effects can carry spin-polarized currents and have gaps in the electronic spectrum in the presence of weak magnetic ...
