  Photoresponsivity enhancement inmonolayer MoS2 by rapid O2:Ar plasma treatment 

  Zhang, Hongzhou; Duesberg, Georg (2019)

  We report up to ten-fold enhancement of the photoresponsivity of monolayer molybdenum disulfide (MoS2) by treatment with O2:Ar (1:3) plasma. We characterize the surface of plasma-exposed MoS2 by TEM, Raman, and PL mapping ...

  The Electro-Optical Performance of Silver Nanowire Networks 

  Ferreira, Mauro (2019)

  Networks of metallic nanowires have the potential to meet the needs of next-generation device technologies that require flexible transparent conductors. At present, there does not exist a first principles model capable of ...

  A comparison of He and Ne FIB imaging of cracks in microindented silicon nitride 

  Zhang, Hongzhou (2018)

  Helium ion microscopy (HIM) offers potential as a high spatial resolution technique for imaging insulating samples that are susceptible to charging artifacts. In this study helium and neon ion microscopy are used to image ...

  Suppression of the Shear Raman Mode in Defective Bilayer MoS2 

  Nicolosi, Valeria; Mc Evoy, Niall; Zhang, Hongzhou (2019)

  We investigate the effects of lattice disorders on the low frequency Raman spectra of bilayer MoS 2. The bilayer MoS 2 was subjected to defect engineering by irradiation with a 30 keV He + ion beam, and the induced morphology ...

  CMEs in the Heliosphere: II. A Statistical Analysis of the Kinematic Properties Derived from Single-Spacecraft Geometrical Modelling Techniques Applied to CMEs Detected in the Heliosphere from 2007 to 2017 by STEREO/HI-1 

  Gallagher, Peter (2019)

  Recent observations with the Heliospheric Imagers (HIs) onboard the twin NASA Solar Terrestrial Relations Observatory (STEREO) spacecraft have provided unprecedented observations of a large number of coronal mass ejections ...
