Transition metal dichalcogenide (TMD) monolayers are 2D semiconductors with direct band gaps. The monolayers can be stacked in various combinations to form heterostructures bonded via weak van der Waals forces . This allows for the formation of interlayer excitons – a quasiparticle consisting of an excited electron in the conduction band of one monolayer, and a hole in the valence band of another . The resultant electric dipole is strong  and can interact with other systems. In my project, I aim to couple interlayer excitons in TMDs with nitrogen-vacancy centres in diamond to create hybrid quantum devices.

I am currently a demonstrator in the 3rd year undergraduate physics laboratory, focusing specifically on the optical pumping experiment which allows for the investigation of the hyperfine structure of rubidium isotopes.
I graduated with an MPhys degree from the University of Leicester in 2021. My 3rd year research project involved modelling a voltage through graphene in C. In my 4th year research I used the DFT modelling program QuantumEspresso to explore the electronic structure and mechanical properties of a theoretical carbon allotrope called pentadiamond. I also applied a similar model to hypothesise its silicon counterpart, pentasilicon.
