Journal ArticleDOI
Direct Observation of Degenerate Two-Photon Absorption and Its Saturation in WS2 and MoS2 Monolayer and Few-Layer Films.
Saifeng Zhang,Ningning Dong,Niall McEvoy,Maria O'Brien,Sinéad Winters,Nina C. Berner,Chanyoung Yim,Yuanxin Li,Xiaoyan Zhang,Zhanghai Chen,Long Zhang,Georg S. Duesberg,Jun Wang +12 more
TL;DR: The giant nonlinearity of WS2 and MoS2 films is attributed to a two-dimensional confinement, a giant exciton effect, and the band edge resonance of TPA.
Journal ArticleDOI
Investigation of the optical properties of MoS2 thin films using spectroscopic ellipsometry
Chanyoung Yim,Maria O'Brien,Niall McEvoy,Sinéad Winters,Inam Mirza,James G. Lunney,Georg S. Duesberg +6 more
TL;DR: In this article, the extinction coefficient and refractive index of layered transition metal dichalcogenide (TMD) thin films grown by vapor phase sulfurization were extracted by developing an optical dispersion model.
Journal ArticleDOI
Noncovalently functionalized monolayer graphene for sensitivity enhancement of surface plasmon resonance immunosensors.
Meenakshi Singh,Meenakshi Singh,Michael Holzinger,Maryam Tabrizian,Sinéad Winters,Nina C. Berner,Serge Cosnier,Georg S. Duesberg +7 more
TL;DR: A highly efficient surface plasmon resonance (SPR) immunosensor is described using a functionalized single graphene layer on a thin gold film to control the immobilization of biotinylated cholera toxin antigen on copper coordinated nitrilotriacetic acid (NTA) using graphene as an ultrathin layer.
Journal ArticleDOI
Preparation of Gallium Sulfide Nanosheets by Liquid Exfoliation and Their Application As Hydrogen Evolution Catalysts
Andrew Harvey,Claudia Backes,Zahra Gholamvand,Damien Hanlon,David McAteer,Hannah C. Nerl,Eva K. McGuire,Andrés Seral-Ascaso,Quentin M. Ramasse,Niall McEvoy,Sinéad Winters,Nina C. Berner,David McCloskey,John F. Donegan,Georg S. Duesberg,Valeria Nicolosi,Jonathan N. Coleman +16 more
TL;DR: In this paper, the authors demonstrate the production of large quantities of gallium sulfide (GaS) nanosheets by liquid exfoliation of layered GaS powder, achieved by sonication of the powder in suitable solvents.
Journal ArticleDOI
Controlled synthesis of transition metal dichalcogenide thin films for electronic applications
Riley Gatensby,Niall McEvoy,Kangho Lee,Toby Hallam,Nina C. Berner,Ehsan Rezvani,Sinéad Winters,Maria O'Brien,Georg S. Duesberg +8 more
TL;DR: In this paper, a facile route to the manufacture of devices from molybdenum (Mo) and tungsten (W) is presented, where highly homogenous TMD films are produced over large areas.
