Dr Tiffany Kaspar

Dr. Kaspar has nearly 20 years of experience with epitaxial oxide deposition by oxygen-plasma-assisted molecular beam epitaxy and pulsed laser deposition at Pacific Northwest National Laboratory (Richland, WA, USA). Her expertise centers on systematic structural characterization of epitaxial films with scattering, spectroscopic, and imaging techniques. This information is then combined with the evaluation of electronic, magnetic, photocatalytic, and/or piezoelectric properties to establish structure-property relationships that provide insight into the physics underlying observed phenomena. The role of intentional and unintentional defects (e.g., dopants, cation and anion non-stoichiometry, misfit dislocations) on oxide structure and properties is a running theme through Dr. Kaspar’s work.
