Personal profile

The PhD is joint with the National Physical Laboratory (NPL) and sets out to investigate graphene using far-infrared excitation. This work is carried out at low temperature and has so far looked at the weak localisation and its suppression by microwaves. More recent work has looked at the effect of MIR radiation on the quantum Hall effect and studied quantum Hall breakdown with noise measurements.

Viktoria obtained her MSci Physics from Royal Holloway in 2012, with a fourth year Master’s project  on the dynamics of the photochemical gating of epitaxial graphene under Deep UV, undertaken at NPL following on from previous summer placements there.

The work undertaken in that period investigated the dynamics of the photochemical gating of epitaxial graphene under Deep UV.  Photochemical gating uses the application of a neutral and an active polymer layer to lower the carrier density of the sample to be used, for instance, in quantum Hall measurements as part of the maintenance of the resistance standard at NPL.

Previous placements at Rutherford Appleton Laboratories saw her work in the Particle Physics group on Serial Powering designs for the LHC upgrade.
