Assistant Professor, 1986 - 1990
Dept. of Physics, University of Texas at El Paso, El Paso, Texas
Established surface and thin film analysis lab with Auger-ESCA-SIMS equipment. Characterized sol-gel method for adding diffusion barriers to a II-VI solar cell process. Studied impurities in a geochemical system (calcite) with Auger, ESCA, and EXAFS. Analyzed metal corrosion problems for local twin-plant industry with ESCA and SIMS. Taught undergraduate and graduate physics.
Physicist (GS-1310-12), 1985 - 1986
U.S. Dept. of Energy, Morgantown Energy Technology Center, Morgantown,
WV
Studied the heterogeneous catalysis of phosphine and related gases using FTIR spectroscopy.
Visiting Assistant Professor, 1983 - 1985
Dept. of Physics, West Virginia University, Morgantown, West Virginia
Prepared and studied ultrathin nickel films on copper substrates with low-energy electron diffraction (LEED) measurements and simulation and with Auger electron spectroscopy. Taught undergraduate physics.
Postdoctoral Research Associate, 1980 - 1983
Dept. of Physics, University of Texas at Austin, Austin, Texas
With Prof. J. L. Erskine, did the first study of the azimuthal-angular dependence of electron scattering in high-resolution electron energy loss spectroscopy (EELS). Taught one introductory course.
Graduate Research Assistant, 1977 - 1980
Dept. of Physics, Univ. of Illinois, Urbana, Illinois
With Prof. Frederick C. Brown, studied charge density waves in layered transition metal dichalcogenides (including semiconductor, semimetal, and metal samples) using angle-resolved ultraviolet photoelectron spectroscopy (ARUPS), low energy electron diffraction (LEED), and X-ray absorption spectroscopy (EXAFS and XANES). With Prof. Franco Bassani, calculated the core exciton binding energy in hexagonal boron nitride for comparison with polarized ultraviolet absorption spectroscopy data.
Engineering Assistant, summers 1974 and 1975
Tektronix, Inc., Beaverton, Oregon
With Dr. Gene Chao, developed Tek's first surface acoustic wave (SAW) device, a TV IF filter with a nonsymmetric bandpass. Programmed FFT calculations of the impulse response (in FORTRAN), devised a mask layout algorithm, and produced output for the pattern generator.
