Fluorocarbon films were deposited on carbon overcoated magnetic recording media from monomers using an ion beam apparatus. The films were characterized using sensitive surface analytical and spectroscopic methods. These include nuclear magnetic reson

We report results of electron paramagnetic resonance, photothermal deflection spectroscopy, and capacitance‐voltage measurements on amorphous hydrogenated silicon nitride (a‐SiNx:H) thin films exposed to ultraviolet (UV) illumination. It has been

SiO2 thin films, deposited by the plasma‐enhanced chemical vapor deposition technique using tetraethylorthosilicate (TEOS) and O2 as precursors, exhibit electron‐paramagnetic‐resonance signals that are interpreted in terms of methyl‐ and dime

The results of a variety of experiments used to characterize fullerenes, metallofullerenes and alkali-metal intercalated C60 are reported. It is shown that differential scanning calorimetry and NMR characterization of the orientational phase transiti

Fullerenes containing metal atoms and clusters can be formed by the arc-vaporization method. The electronic structure of these metallofullerenes can be probed using magnetic resonance techniques. Electron paramagnetic resonance (EPR) spectra of LaC82

Two dominant electron paramagnetic resonance (EPR) hyperfine patterns for both La and Y fullerenes have been identified and linked to the mass spectroscopic (MS) peaks of La@C 82 and Y@C 82 , respectively, as also observed by Suzuki. Additionally, lo

Process parameters that affect the reactive ion etching of PECVD n+ a‐Si:H film have been studied. The n+ a‐Si:H etching mechanism is similar to that of a‐Si:H etching, e.g., both plasma phase chemistry and ion bombardment are contributing fact

Solid fluorocarbon films were deposited on carbon overcoated magnetic recording media. The films were made by direct ion beam deposition of fluorocarbon monomers. This paper presents ellipsometric measurements on films over a range of thickness from

We investigated a new lubricant made using ion beam assisted deposition of fluorinated monomers. The fluorocarbon film is referred to as ion beam lubricant, IBL. Typical thin film media deposition was followed by deposition of the IBL. The IBL provid
