Detection of ultra-low concentration NO2 in complex environment using epitaxial graphene sensors
Christos Melios, Vishal Panchal, Kieran Edmonds +3
We demonstrate proof-of-concept graphene sensors for environmental monitoring of ultra-low concentration NO2 in complex environments. Robust detection in a wide range of NO2 concen…
Visualisation of edge effects in side-gated graphene nanodevices
Vishal Panchal, Arseniy Lartsev, Alessandra Manzin +3
Using local scanning electrical techniques we study edge effects in side-gated Hall nanodevices made of epitaxial graphene. We demonstrate that lithographically defined edges of th…
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…
