Graphene Meets Diamond: 2d Spintronics Probed With Diamond Quantum Sensors

Grant number: DE170100129 | Funding period: 2017 - 2020

Completed

Abstract

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. However, for its full potential to be reached, techniques are needed to directly probe and image spins in operating devices. The project plans to exploit recently developed diamond quantum sensing technologies to characterise graphene spintronic devices. The results and methods are expected to clarify the underlying microscopic mechanisms and provide a route to design and optimise functional graphene spintronic devices.
