Michael J Zachman

R&D Associate

Michael Zachman is a Staff Scientist in the Center for Nanophase Materials Science (CNMS) at Oak Ridge National Laboratory (ORNL). He received his B.S. in Physics from Purdue University in 2012, and his Ph.D. in Applied Physics from Cornell University in 2018. Michael’s research interests lie in advancing electron microscopy techniques to enable understanding of the structure and properties of quantum and energy materials down to the atomic scale. His doctoral work concentrated on developing cryogenic focused ion beam (cryo-FIB) and aberration-corrected analytical scanning transmission electron microscopy (cryo-STEM) techniques to study processes at solid-liquid interfaces at high spatial resolution with the liquids intact. He applied these techniques to energy materials and energy storage devices to gain unique insights into processes such as solid-electrolyte interphase (SEI) layer and dendrite formation in lithium metal batteries (LMBs). Michael's postdoctoral research concentrated on developing and applying multi-dimensional STEM techniques and monochromated electron energy-loss spectroscopy (EELS) to two-dimensional and battery materials to study their structure and properties at the nanometer and atomic scale. Michael's research currently focuses on adapting and pairing techniques such as these to enhance the understanding of processes that contribute to fuel cell material performance and degradation, enabling improvement of existing materials and development of new materials.
