The scientific basis for the understanding of deposition parameters, microstructure and properties of aluminum nitride thin films has been established. The films were prepared by sputtering and characterized by XRD, Raman spectroscopy, reflectometry, ellipsometry, curvature measurement for stress determination, photoluminescence, AFM, and SEM. Novel techniques for quantifying the piezoelectric and acoustic properties were developed, utilizing Surface Acoustic Wave devices, pyroelectric measurements, and direct piezoelectric measurements via vibrometry, in combination with Finite Element Modeling. Novel approaches to non-destructively predict devices performances were proposed. The context of this project was an interdisciplinary research effort involving electrical engineering, mechanical engineering and materials science, and aimed at the fabrication of MEMS-based resonators for Ultra High Frequency filtering applications in telecommunications. The team successfully designed, simulated and fabricated novel mechanical resonators utilizing the piezoelectric properties of AlN thin films.  Thermal Barrier Coatings for Energy Efficient Engines.This work was part of an interdisciplinary effort for developing Thermal Barrier Systems aimed at enhancing the operating temperature and therefore the efficiency of turbine engines. The phase stability of the outer layer of the Thermal Barrier System, a coating of stabilized zirconium oxide, was investigated via Raman spectroscopy and X-Ray Diffraction. January 1997 – December 1999 Undergraduate Research Assistant – Materials Department, University of Trieste, Italy  Raman Spectroscopy for ceramic materials characterization. Raman and fluorescence spectroscopic techniques have been used to perform phase analysis and measurement of residual stresses (piezo-spectroscopy) in a wide variety of materials: silicon, aluminum oxide, zirconium oxide, silicon nitride, PZT. In particular, the ability of mapping residual stress and phase composition on a microscopic scale has been demonstrated, as well as the innovative use of confocal techniques in Raman piezo-spectroscopy.
