BROSYNANO: EXPERIMENTAL STUDY OF TUNABLE SPIN AND VALLEY DEGENERACY IN BROKEN-SYMMETRY NANOSYSTEMS (PID2019-106820RB-C22)
Abstract:
We will focus on graphene and heterostructures of 2D materials as well as topological insulators and chiral molecular systems, where charge, spin transport and spin-light interactions are prominent and controllable. Essential ingredients of the underlying physics are broken-symmetry, chirality and topology. Nevertheless, the theoretical underpinning of topological and chiral spintronic materials is still being developed and understood. The project includes both experimental and theoretical aspects, closely linked as we will describe in this proposal. Besides their undoubted fundamental interest, our scientific advances can pave the way for future breakthroughs in quantum technologies.Furthermore, both nanodevice fabrication for transport studies and measurement of optoelectronic properties of nanostructures are needed to elucidate the underlying science of topological and chiral spintronics. All of these factors together make the field a particularly challenging one, requiring a grasp of diverse expertise. We believe that the best scientific work is based on research at the cutting edge and all of the interlinked projects tackle problems at the forefront of topological and chiral spintronics research, both theoretical and experimental. The structure of the present proposal is built around extensive cross-linking, which will allow us to develop a broad view alongside their specialty work.
