A comparison of radio-frequency (rf) glow discharges at 13.56 megahertz between dielectric electrodes in an Argon environment with discharges between aluminum electrodes reveals that the discharge amplitude in dielectric electrodes is less than that for metal electrodes. The rf glow discharges are determined by spatiotemporal optical emission spectroscopy. The total excitation rate is different for the two types of electrodes and is revealed as peaks in the anodic and cathodic cycle of the electrodes.

Presents a study that examined the crystalline quality of germanium (Ge) films grown on a silicon substrate by molecular beam epitaxy. Analysis of the change of the mean in-plane lattice constant of the Ge films; Evaluation of the x-ray diffraction pattern of the thin films; Examination of the Raman scattering spectra of the thin films.

Presents a study which deposited crack-free transparent ferroelectric lanthanum-doped lead zirconate titanate (PLZT) thin films on silicon substrates using the sol-gel deposition technique. Method and materials used in preparing silicon wafer samples; Approach used in the wet chemical etching of the samples; Observation on the wave guiding properties of the PLZT.
