I am a materials scientists who uses X-rays sources to study structure and chemistry in novel materials for future energy-efficient memory technology.
My current research focuses on the characterisation of metal-oxide resistive switching thin films. These films are of interest for non-volatile memory, which is required to reduce the power used for data storage and transfer. Developing low power memory is critical to accommodate our every growing data needs (with data centres projected to consume 10-20% of global electricity by 2030).
By using my expertise in synchrotron-based X-ray imaging, I hope to learn more about the atomistic mechanisms that control these memory devices. This involves the investigation of chemical changes during device operation, via operando X-ray spectroscopy. I am also interested in how strain and structure can effect device performance, which I can investigate using nano-focused X-ray probes at synchrotrons. Having a fundamental understanding of device operation will allow us optimise materials growth and overall film performance. Further, developing these state-of-the-art characterisation techniques will enable the study of other energy materials such as solid-state batteries. Ultimately, I hope to use my materials characterisation expertise to contribute to the creation of a more environmentally-friendly technological world.
