James Nunn

Background

I graduated from the University of Warwick in summer 2019 with a BSc MPhys in Physics. My final year project involved using scanning and transmission electron microscopy techniques to analyse the structural and optical properties of nanowire heterostructures, completed under the supervision of Prof. Ana Sanchez of the Microscopy group. Currently I am completing my PhD joint with the Microscopy group at the University of Warwick, with supervision by Prof. Neil Wilson, and the I05 beamline at Diamond Light Source, with supervision by Dr Cephise Cacho.

Research Interests

My research is currently focused around 2D materials and van der Waals heterostructures, specifically using angle-resolved photoemission spectroscopy (ARPES) to investigate their layer-dependent band structure and interlayer effects. This requires the use of a spatially-resolved ARPES beam, available only at select synchrotron beamlines. An extension of this work is also to use in situ electrostatic gating to visualize the conduction band of 2D semiconductors, as well as observe band structure renormalisation effects. I have predominantly looked at heterostructures consisting of graphene and transition metal dichalcogenides (TMDs), but plan to extend this to looking at 2D materials with more exotic phenomena, such as 2D magnetism.
