Research Interests:The focus of our research is on surfaces, interfaces, and films of technically important materials. We work to establish relationships between the processing parameters, the material properties, and finally the performance of the film in its proposed application. We create films using chemical vapor deposition and characterize them using spectroscopic ellipsometry, medium energy ion beam backscattering, Rutherford backscattering spectrometry, Auger electron spectroscopy, x-ray photoelectron spectroscopy, and x-ray diffraction. We currently have three project thrusts.
UHV-CVD reactor used for process-property-performance studies.
- UHV-CVD of Alumina and Zirconia thin films for high-permittivity gate dielectrics. Application- CMOS transistors.
- Understanding the effects of high temperature, dissociated oxygen/nitrogen environments on ultra-high temperature ceramic composites (eg. Hf(Zr)B 2 /SiC). Application- Sharp leading edges and control surfaces for hypersonic flight.
- Engineer coatings that will perform in high-temperature, high-flow, reactive environments. Applications: Carbon composites for use in harsh environments
