Bio

Salvador's energy related research develops materials for advanced energy conversion technologies, including electrodes in solid oxide fuel cells and catalysts for solar fuel production. 

Professor Salvador received his B.S.E. in Materials Science and Engineering from the University of Pennsylvania in 1992 and his Ph. D. in Materials Science and Engineering from Northwestern University in 1997. He then spent two years in France as a post-doc at the Ecole Nationale Supérieure d'Ingénieurs (ENSI) de Caen, ISMRA (Laboratoire Crismat), working in the area of Materials Science and Solid State Chemistry. He joined Carnegie Mellon in 1999 as an Assistant Professor in the Department of Materials Science and Engineering, where he is currently a Professor. Salvador Biographical Information

Research

Professor Salvador's research interests lie in the areas of thin film synthesis/growth, characterization, and architectural design of inorganic crystalline materials. His current focus is on the design of materials having structural features engineered from the sub-nanometer to the micron length scale. His group uses pulsed laser deposition and molecular beam epitaxy to grow crystals of oxides, nitrides, oxynitrides, metals, and composites (or heterostructures) of those materials for a variety of applications in the fields of energy, information storage, hard coatings, and RF electronics. Examples of research areas include surface engineering of catalysts used in chiral separations, solid oxide fuel cells, and solar hydrogen composites; determination of structure-property relationships in heterostructured films for probe data storage; design of nanostructured superlattice thin films for hard coatings, RF circuits, and information storage; thin film synthesis of metastable and artificially layered ferroelectric, dielectric, and magnetic crystals; the design of multifunctional (and/or multiferroic) materials using chemical principles and thin film processing; and the determination the evolution of microstructures in thin films and solid oxide fuel cell cathodes.
