Thursday 13 Oct 2016 NEST Seminar: Studies of local electronic properties of graphene

Dr. Olga Kazakova - National Physical Laboratory

HAR/170 (3D Visualisation Suite)  12:30-13:30

We present a quantitative method for the mapping of local electronic properties of graphene and related materials. We also demonstrate that the technique is essential both for control of growth parameters and device functionality. The approach combines local mapping of graphene work function and structural properties on the nanoscale, with measurements of global magnetotransport characteristics.
The results are shown by the charge inversion in quasi-free graphene and the effects of humidity and environment in graphene chemical sensors.
