Semiconductors form an important part of our society, being critical to all facets of electronics and photonics. My research centres on lead halide perovskites, a class of highly functional semiconductors that can be processed into high-quality thin films and integrated into a wide range of optoelectronic and photonic applications.
My work focuses on the growth of perovskite semiconductors by thermal vapour deposition, a scalable fabrication technique capable of producing highly uniform thin films over large areas. By investigating the relationships between deposition conditions, microstructures, and photo-physical properties, I aim to develop these low-cost semiconductor materials to be well-suited for both next-generational energy-harvesting and light-emitting technologies.
A major theme of my research is the development of perovskite lasers. Utilising both ultrafast optical spectroscopy and advanced materials characterisation, I study how the structural and optoelectronic properties of vapour-deposited perovskites influence fundamental light-matter interactions and optical gain characteristics. These insights contribute towards the development of coherent and scalable light sources.
Alongside photonic applications, I am also interested in the use of vapour-deposited perovskites for efficient solar cells. Through a combination of thin-film growth optimisation, solar cell device spectroscopy (such as Fourier Transform Photocurrent Spectroscopy), and atomic-resolution electron microscopy, my research seeks to establish fundamental design principles for establishing the perovskite absorber as a reliable source of renewable energy.
I completed both my undergraduate MPhys degree and DPhil in Condensed Matter Physics at Oxford. I am currently affiliated with Jesus College as a Stipendiary Lecturer in Physics.
