Dengyu Yang (IntlAssoc)

Dengyu Yang is an associate researcher in the Nanoscale Processes and Measurements Group in the Physical Measurement Laboratory (PML) at NIST and a Joint Quantum Institute (JQI) postdoctoral research associate. She received her B.S. in Applied Physics from the Beijing Institute of Technology and her Ph.D. in Physics from the University of Pittsburgh, where her doctoral thesis is about reprogrammable quantum materials. During her Ph.D., Dengyu and her advisor Professor Jeremy Levy developed ultra-low-voltage electron beam lithography (ULV-EBL) for nanoscale patterning of quantum materials on complex oxide heterointerfaces and ferroelectric materials. She also studied surface acoustic waves (SAW) and superconducting devices, including single-electron transistors (SETs) and electron waveguides at SrTiO3-based heterostructures. Prior to joining NIST, she conducted postdoctoral research at Carnegie Mellon University, where she employed these quantum material programming techniques on ferroelectric substrates and studied van der Waals materials (such as graphene) on the programmed substrates to enable band engineering.

At NIST, under the guidance of advisor Joseph Stroscio, Dengyu’s passion is on using electron spin resonance scanning tunneling microscopy (ESR-STM) system to probe the physical properties of unprogrammed and programmed two-dimensional quantum materials, including complex oxide two-dimensional electron gas and van der Waals systems. With a technical background of cryogenic temperature transport measurement, scanning probe microscopy and advanced lithography, and a material background of complex oxides, ferroelectric materials and van der Waals materials, Dengyu aims to address fundamental questions in quantum physics while advancing practical applications of quantum materials.
