Probing the nanoscale origin of strain and doping in graphene-hBN heterostructures
Tom Vincent, Vishal Panchal, Tim Booth +4
We use confocal Raman microscopy and modified vector analysis methods to investigate the nanoscale origin of strain and carrier concentration in exfoliated graphene-hexagonal boron…
Unique excitonic effects in tungsten disulphide monolayers on two-layer graphene
Cristina E. Giusca, Ivan Rungger, Vishal Panchal +8
Light emission in atomically thin heterostructures is known to depend on the type of materials, number and stacking sequence of the constituent layers. Here we show that the thickn…
Water affinity to epitaxial graphene: the impact of layer thickness
Cristina E. Giusca, Vishal Panchal, Martin Munz +5
The sensitivity to water of epitaxial graphene is examined in this study.
Water on graphene: Review of recent progress
Christos Melios, Cristina E. Giusca, Vishal Panchal +1
The sensitivity of graphene to the surrounding environment is given by its π electrons, which are directly exposed to molecules in the ambient. The high sensitivity of graphene to…
Tuning epitaxial graphene sensitivity to water by hydrogen intercalation
Christos Melios, Michael Winters, Wlodek Strupinski +6
The effects of humidity on the electronic properties of quasi-free standing one layer graphene (QFS 1LG) are investigated via simultaneous magneto-transport in the van der Pauw geo…
Atmospheric doping effects in epitaxial graphene: correlation of local and global electrical measurements
Vishal Panchal, Cristina E. Giusca, Arseniy Lartsev +5
We directly correlate the local (20-nm scale) and global electronic properties of a device containing mono-, bi- and tri-layer epitaxial graphene (EG) domains on 6H-SiC(0001) by si…
