Dr. Yingge Du is a senior staff scientist in the Materials Group of the Physical and Computational Sciences Directorate. He joined PNNL in 2007 and became a staff member in 2010. He served as technical lead in the acquisition and commissioning of a new state-of-the-art oxide molecular beam epitaxy (MBE) system for the EMSL user facility located at PNNL. His current research focuses on growth and characterization of epitaxial metal oxide films and superlattices for energy conversion and storage applications.

Dr. Du is the recipient of a 2016 DOE Early Career Award. This award will support him to conduct basic research that aims to understand, predict, and ultimately control cation/anion ordering and topotactic phase transitions occurring in transition metal oxide thin films. Achieving so will enable energy materials (e.g., catalysts, electrodes, and electrolytes) with desired functionalities to be designed, synthesized, stabilized, and harnessed for technological benefits.
