Michael Stewart (Fed)
Michael Stewart is an experimental physicist at the National Institute for Standards and Technology (NIST) in the Atom Scale Devices Group. He performs fundamental research in silicon single electron devices to build a standard of the electrical current based on the elementary charge, and for use as qubits in the solid state. He is focused on fabrication methods, materials, and measurement techniques which give stable, clean devices with high yield. This work involves fabricating and measuring the impact of device design, materials choices, and defect levels on device performance to remove deleterious effects while also designing measurement techniques which mitigate those effects. Moreover, we perform single electron pumping measurements and quantum coherent measurements while working on techniques to integrate devices together. Dr. Stewart graduated from Brown University with a M.S. and Ph.D. in physics and received his undergraduate degree in physics and mathematics from the University of Wisconsin - Madison.
