Current Research:

Van der Waal stuctures are fabricated by layering 2D materials on top of each other, much like Lego. However, this introduces a new degree of freedom: twist angle. It has been shown that twist angle can have important effects on the properties of the structure. For example magic angle twisted bilayer graphene can be a Mott insulator or a superconductor depending on its carrier density, but only at the magic angle [1]. For a group of semiconducting 2D materials called transition metal dichalcogenides, the twist angle is predicted to result in single photon emitters [2]. These emitters have a variety of applications, particularly to quantum communication and quantum computing [3,4]. My project is to isolate the emitters from eachother, such that only one emitter actually emits when the Van der Waal structure is excited with a laser.

I studied my MSci at King's College London, where my third year project was on computationally modelling supersonic flow, while my Masters project was a DFT investigation into the properties of thin film perovskite materials. This last project developed my interest in low dimensional materials, particularly applications to the electronics industry and quantum technology.
