Research Interests:

I am using time-resolved spectroscopy techniques to investigate charge transport in metal halide perovskites (MHPs). MHPs are a class of semiconducting materials that have great potential as absorbers in next-generation solar cells due to their outstanding optoelectronic properties. In particular, I am interested in using terahertz radiation to probe the transient photoconductivity of MHPs at picosecond timescales using Optical-Pump Terahertz-Probe spectroscopy (OPTP), as shown in the diagram below. This technique allows the mobility and time evolution of a photo-generated population of charge carriers to be investigated.

My speciality is studying charge carrier dynamics in quasi-2D layered MHP materials whereupon electronic confinement within the layers profoundly impacts the dynamics of photo-excited charge carriers.

I am a final-year PhD Student in the Ultrafast and THz photonics research group which I joined in the summer of 2019. Prior to this I received an MPhys degree in Physics from Corpus Christi College, Oxford. My fourth-year project was supervised by Prof. Henry Snaith and Dr. Bernard Wenger of the Photovoltaic and optoelectronic device group. I constructed apparatus for electroluminescence imaging of metal halide perovskite optoelectronic devices. Using this system I studied devices created by other group members such as 2D/3D hybrid perovskite LEDs and large surface area perovskite solar cells. This experimental tool proved valuable for investigating spatial inhomogeneity and long-term transient changes in the devices; in addition to rapid, non-destructive quality control.

Teaching Activities:

I am currently a demonstrator in the second-year undergraduate electronics lab.
