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

The emergence of flexible nanoelectronics holds the promise to impact the way we live—from smart wearables to foldable smartphones. However, heat dissipation in the atomically-thin materials used for their conception has remained poorly understood due to their planar structures. This project aims at the detection and mapping of nanoscale thermal hotspots in flexible nanoelectronics devices using a two-dimensional-based optical thermometer. The expected outcome of this project is the development of a non-invasive thermometric technology that enables locating these critical nanoscale hotspots with nanoscale precision. This will lead to better design and manufacturing strategies for heat dissipation in these devices.Read moreRead less
