Controlled synthesis of transition metal dichalcogenide thin films for electronic applications
REZVANI, EHSAN; LEE, KANGHO; BERNER, NINA; MCEVOY, NIALL; HALLAM, TOBY; DUESBERG, GEORG (2014)Two dimensional transition metal dichalcogenides (TMDs) are exciting materials for future applications in nanoelectronics, nanophotonics and sensing. In particular, sulfides and selenides of molybdenum (Mo) and tungsten ... -
Effect of percolation on the capacitance of supercapacitor electrodes prepared from composites of manganese dioxide nanoplatelets and carbon nanotubes
COLEMAN, JONATHAN; BERNER, NINA; DUESBERG, GEORG; NICOLOSI, VALERIA; MCEVOY, NIALL (2014)Here we demonstrate significant improvements in the performance of supercapacitor electrodes based on 2D MnO2 nano-platelets by the addition of carbon nanotubes. Electrodes based on MnO2 nano-platelets do not display high ... -
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 ... -
Transition metal dichalcogenide growth via close proximity precursor supply
COLEMAN, JONATHAN; DUESBERG, GEORG; HALLAM, TOBY; MCEVOY, NIALL; KIM, HYE; BERNER, NINA; LEE, KANGHO (2015)Reliable chemical vapour deposition (CVD) of transition metal dichalcogenides (TMDs) is currently a highly pressing research field, as numerous potential applications rely on the production of high quality films on a ...
