Description
This fellowship opportunity at the National Institute of Standards and Technology (NIST) focuses on advancing the understanding and performance of quantum anomalous Hall effects (QAHE) and topological insulators (TI) through high-frequency studies in the GHz and THz ranges. The QAHE is significant for metrology as it offers a quantum standard of resistance at the value of h/e², arising from the topological complexity of 2D materials such as magnetically-doped topological insulators and twisted multilayer graphene.
NIST's ongoing research includes fabrication, measurement, and high-accuracy determination of these phenomena. However, practical limitations such as temperature constraints and electrical behavior issues remain. High-frequency investigations aim to elucidate energy splittings and mechanisms that limit QAHE performance, potentially leading to improved quantum resistance standards. More broadly, these studies probe the complex physics of various topological insulators, including strongly interacting phases.
Principal Investigators include Neil Zimmerman, Curt Richter, and Nikolai Zhitenev.
