Overview
I am a PhD Student working in the Quantum Devices group at Cardiff. My research focuses on integrating superconductors with semiconductor micro-electronics for Quantum Computing applications. This involving designing, making and testing novel devices to explore the superconductor/semiconductor interface.

Research interests
My work involves integrating superconducting films with semiconductor heterostructure devices:
- I primarily investigate the proximity induction of superconductivity in InSb quantum well heterostructures via deposition of thin (<100nm) films of superconductors, such as Nb, Al and Pb.
- This investigation is done by using a modified Transmission Line measurement to attempt to directly measure the length of the proximity induced superconducting state.
- I have also investigated the nature of the superconducting pairing at the Superconductor/semiconductor interface via Muon Spin Relaxation using the Low Energy Muon beamline at the Paul Scherrer Institute.
- A measurement on a Nb/InSb 2DEG heterostructure has been performed, with a follow on measurement on Pb/InSb scheduled for late 2022.
- I also work on fabrication of side gates to allow the creation of a 1D conductance state via electrical confinement of InSb 2DEGs via use of a plasma FIB etching in collaboration with the University of Surrey.
