Steffi Y Woo

R&D Staff Scientist



Dr. Steffi Woo is a R&D Associate in the Center for Nanophase Materials Sciences at Oak Ridge National Laboratory. She has a B.Eng. in Materials Engineering and Society with a minor in Chemistry from McMaster University (Canada). She obtained her M.A.Sc. in Materials Engineering for her thesis work on the characterization of extended defects in group III-V semiconductor thin films by conventional TEM also at McMaster University in the group of Prof. Gianluigi Botton. Her Ph.D. work focused on the structural and chemical variations in group III-nitride nanowire heterostructures, also supervised by Prof. Botton. She was previously a post-doctoral researcher in the STEM group at the Laboratoire de Physique des Solides in Orsay (France) with a focus on the optical response of 2D materials, including h-BN and transition metal dichalcogenides using electron energy-loss spectroscopy (EELS) and cathodoluminescence.
