Perforating Freestanding Molybdenum Disulfide Monolayers with Highly Charged Ions
Mc Evoy, Niall; Duesberg, Georg (2019)Porous single-layer molybdenum disulfide (MoS2) is a promising material for applications such as DNA sequencing and water desalination. In this work, we introduce irradiation with highly charged ions (HCIs) as a new technique ... -
PtSe2 grown directly on polymer foil for use as a robust piezoresistive sensor
Duesberg, Georg (2019)Robust strain gauges are fabricated by growing PtSe2layers directly on top of flexible polyimide foils. These PtSe2layers are grown by low-temperature, thermally-assisted conversion of predeposited Pt layers. Under applied ... -
Quantum confinement-induced semimetal-to-semiconductor evolution in large-area ultra-thin PtSe2 films grown at 400 °C
Duesberg, Georg (2019)In this work, we present a comprehensive theoretical and experimental study of quantum confinement in layered platinum diselenide (PtSe2) films as a function offilm thickness. Our electrical measurements, in combination ... -
Rapid and Large-Area Visualization of Grain Boundaries in MoS 2 on SiO 2 Using Vapor Hydrofluoric Acid
Duesberg, Georg (2020)Grain boundaries in two-dimensional (2D) material layers have an impact on their electrical, optoelectronic, and mechanical properties. Therefore, the availability of simple large-area characterization approaches that can ... -
Site-Selective Oxidation of Monolayered Liquid-Exfoliated WS2 by Shielding the Basal Plane through Adsorption of a Facial Amphiphile
Duesberg, Georg (2020)In recent years, various functionalization strategies for transition‐metal dichalcogenides have been explored to tailor the properties of materials and to provide anchor points for the fabrication of hybrid structures. ... -
Slippery polymer monoliths: Surface functionalization with ordered MoS2 microparticle arrays
Duesberg, Georg (2021)components of technical systems and devices often require self-lubricating properties, which are implemented by means of dry lubricants. However, continuous lubricant coatings on the components’ surfaces often ... -
Sub-millimeter size high mobility single crystal MoSe2 monolayers synthesized by NaCl-assisted chemical vapor deposition
Duesberg, Georg (2020)Monolayer MoSe2 is a transition metal dichalcogenide with a narrow bandgap, high optical absorbance andlarge spin-splitting energy, giving it great promise for applications in thefield of optoelectronics. Producingmonolayer ... -
Synthesis and characterisation of thin-film platinum disulfide and platinum sulfide
Duesberg, Georg; Mc Closkey, David; Mc Evoy, Niall (2021)Group-10 transition metal dichalcogenides (TMDs) are rising in prominence within the highly innovative field of 2D materials. While PtS2 has been investigated for potential electronic applications, due to its high ... -
Template-free and surfactant free solvothermal synthesis of mesoporous manganese oxide with enhanced activity in the oxygen evolution reaction
Lyons, Michael; Colavita, Paula; Duesberg, Georg (2017)Porous manganese carbonate was obtained via solvothermal synthesis using ethanol and urea. The manganese carbonate was subsequently used as a precursor to synthesise mesoporous manganese oxides via thermal treatments at ... -
