Charge and Spin Transport in Strongly Correlated Low Dimensional Quantum Heterostructures
Harnessing the symmetry protected electron states observed in quantum materials is a grand challenge for the future of nanoelectronics. Low dimensional van der Waals materials possess novel and topologically protected spin and valley states that allow for coherent propagation of charge and spin over large distances. Yet, it remains a challenge to enhance, manipulate, and control these novel states. Here we will leverage our team’s expertise in van der Waals heterojunctions and thin film epitaxy to develop novel hybrid heterointerfaces between low dimensional topologically non-trivial materials and strongly correlated complex oxides. Using variable temperature magnetometry and magnetotransport measurements, our team will develop a fundamental understanding and control of the mechanisms underlying the interplay between charge, structure, and spin in these heterostructures. Specifically, we seek to explore charge transfer, carrier density modulation, and magnetic exchange coupling across the interface and the resulting interfacial spin structures and spin-transport. Our multi-interdisciplinary team is composed of recognized experts in the areas of thin film epitaxy, magneto- and spin transport in strongly correlated systems, and charge transport of optically excited states in 2D materials.
