Abstract : An interdisciplinary research team of A&T Physics and Chemistry faculty and students (undergraduate) successfully deposited thin diamond-like carbon (DLC) films on substrates provided them by ARDEC, as proposed. The substrates included aluminum, alumina, copper and copper chromium. The films were grown by the Plasma Enhanced Chemical Vapor Deposition (PECVD) method using a deposition system by Technics, Inc. The films were characterized by their indices of refraction (measured using a Gaertner L - 117 ellipsometer) and their Raman Spectra (measured using a spectrometer at the University of North Carolina at Chapel Hill, Chapel Hill, NC). Graduate studies (1 M.S., 1 Ph.D.) dissertations were developed from this study. The M.S. thesis was completed by and A&T Chemistry student by the close of this project. Important dielectric studies were done by the Ph.D. graduate student at the Institute of Advanced Technology at the University of Texas at Austin, Austin, TX.
