Electroanalytical Sensing Properties of Pristine and Functionalized Multilayer Graphene
Duesberg, Georg; Mc Evoy, Niall (2014)This paper describes the heterogeneous electron transfer (ET) properties of high-quality multilayer graphene (MLG) films grown using chemical vapor deposition (CVD) on nickel and transferred to insulating poly(ethylene ... -
Few-Layer MoS2/a-Si:H Heterojunction Pin-Photodiodes for Extended Infrared Detection
Mc Evoy, Niall; Duesberg, Georg (2019)Few-layer molybdenum disulfide (FL-MoS2) films have been integrated into amorphous silicon (a-Si:H) pin-photodetectors. To achieve this, vertical a-Si:H photodiodes were grown by plasma-enhanced chemical vapor deposition ... -
Grain boundary-mediated nanopores in molybdenum disulfide grown by chemical vapor deposition
Duesberg, Georg; Mc Evoy, Niall (Royal Society of Chemistry, 2017)Molybdenum disulfide (MoS2) is a particularly interesting member of the family of two-dimensional (2D) materials due to its semiconducting and tunable electronic properties. Currently, the most reliable method for obtaining ... -
Growth of 1T′ MoTe2 by Thermally Assisted Conversion of Electrodeposited Tellurium Films
MC MANUS, JOHN BRENDAN; Mc Evoy, Niall; Duesberg, Georg; Shvets, Igor (2019)Molybdenum ditelluride (MoTe2) is a transition metal dichalcogenide (TMD) which has two phases stable under ambient conditions, a semiconducting (2H) and semimetallic (1T′) phase. Despite a host of interesting properties ... -
Helium ion microscope generated nitrogen-vacancy centres in type Ib diamond
Zhang, Hongzhou; Mc Closkey, David; Duesberg, Georg; Donegan, John; Mc Evoy, Niall; Cross, Graham (2014)We report on position and density control of nitrogen-vacancy (NV) centres created in type Ib diamond using localised exposure from a helium ion microscope and subsequent annealing. Spatial control to <380 nm has been ... -
Highly Selective Non-Covalent On-Chip Functionalization of Layered Materials
Duesberg, Georg; Mc Evoy, Niall (2021)Non-covalent functionalization of layered 2D materials is an essential tool to modify and fully harness their optical, electrical, and chemical properties. Herein, a facile method enabling the selective formation of ... -
