About
Dr. Le Wang is a senior Materials Scientist in the Materials Sciences group of the Integrated Discovery Sciences Directorate (IDSD) at PNNL and a recipient of the 2025 U.S. Department of Energy Early Career Research Program (ECRP) award. His research focuses on growing epitaxial oxide thin films and heterostructures and investigating their applications in microelectronics, spintronics, ion transport, and electrocatalysis. He uses X-ray photoelectron and absorption spectroscopy to probe the electronic structure of these complex oxide thin films and relate the spectroscopic data to their structure and properties, with the goal of better understanding the composition-structure-property-stability relationships.
Le has published more than 80 peer-reviewed articles in journals including Science Advances, Nature Communications, Advanced Materials, Physical Review Letters, Nano Letters, and ACS Nano. He has also served as a lead symposium organizer for the Materials Research Society (MRS) Spring Meeting, ACerS Spring Meeting, and as a reviewer for journals including Nature Materials, Nature Communications, Advanced Functional Materials, Small, and journals in the ACS portfolio.
