Synthesis of enriched silicon for long-lived donor quantum states. We have discovered a method to make silicon highly enriched in the desirable spin-zero isotope using readily available ion implantation tools.

We have discovered a method to make silicon highly enriched in the desirable spin-zero isotope using readily available ion implantation tools. This “semiconductor vacuum” is essential for building future quantum computer devices using the quantum spin of millions of implanted atoms with revolutionary capabilities. We have demonstrated long-lived implanted donor atom quantum states in prototype material, made possible by the depletion of background spins in natural silicon and now aim to push the enrichment to greater extremes. We will integrate the extreme material into functional devices that use electrically detected electron spin resonance to probe exceptionally durable quantum states and open a near-term pathway to large-scale devices.Read moreRead less

This project aims to create a universal, high-throughput platform to characterise magnetic 2D materials, by exploiting recently developed quantum diamond microscopy. It will enable the measurement of hitherto inaccessible magnetic properties of individual 2D microsheets, the imaging of device-relevant phenomena such as domain wall dynamics and skyrmionics, and the systematic screening of newly synthesised materials. Anticipated outcomes include crucial new insights into 2D magnetism and the discovery of magnetic 2D materials compatible with real-world conditions. This should accelerate the development of future energy-efficient and flexible electronics and memory technologies, where magnetic 2D materials are expected to play a key role.

This project aims to develop new electron microscopy techniques that will unambiguously determine the elusive structures of photoactive perovskite compounds under static and operational conditions, while correlating crystal structure with solar cell device performance. Photoactive perovskites are promising photovoltaic materials, however, many are sensitive to air and irradiation. This has impeded a huge international research effort to determine their structure reliably at the atomic scale. With these new techniques applied to leading compounds and devices, it is expected this project will reveal the structural effects controlling electrical properties and device performance and so enable the design of superior perovskite photovoltaics.Read moreRead less

Two-dimensional spintronics probed with diamond quantum sensors. This project aims to understand the spintronic properties of graphene. Graphene, a ground-breaking two-dimensional material, has tremendous potential for the realisation of high-speed, low-power operation, spin-logic devices for next-generation electronics.

This project aims to investigate the role of local atomic structure in the formation and mechanical properties of glasses by applying newly developed structure-determination methods.
