- Deposition of Fluorine-Containing Thin Film by Atmospheric Pressure Plasma Jet and Film Surface Structural Transition
Wei-Chun Ma, Chin-Ho Lin and Chun Huang

This study shows that atmospheric-pressure plasma jet offered the capable deposition technique for SiOxCyFz thin film growth. It is found that the working distance of atmospheric-pressure plasma polymerization dominates the surface morphological change and chemical structure transition of polymerized thin films.
- Determination of the Electron Density in an Argon Plasma Jet Using Absolute Measurements of Continuum Radiation

This paper is about determination of the electron density of an argon plasma jet using the continuum radiation. The method provides electron density values of about 7 × 1019 m−3 in the active zone for a plasma created by a sinusoidal voltage of 10 kVpp. The electron density decreases in the afterglow direction down to 2 × 1017 m−3.
- Molecular Dynamics Calculations of CH3 Sticking Coefficient onto Diamond Surfaces
Laurent Schwaederlé, Pascal Brault, Cathy Rond and Alix Gicquel

Efficient processing of diamond single crystal deposition by moderate pressure and power microwave plasma requires knowledge of important basic data, among them the sticking coefficients of the main deposition precursors. This work provides molecular dynamics simulations for a rigorous of the methyl radical sticking coefficient on hydrognated diamond single crystal substrate.
- Polyimide Film Surface Modification by Nanosecond High Voltage Pulse Driven Electrical Discharges in Water
Camelia Miron, Camelia Hulubei, Ion Sava, Antje Quade, Anna Steuer, Klaus-Dieter Weltmann and Juergen F. Kolb
Article first published online: 23 FEB 2015 | DOI: 10.1002/ppap.201400170
Nanosecond pulsed electrical discharges generated in distilled water are used to modify the surface of the aromatic and partially aromatic polyimide films. The reactive species formed by plasma submersed in water have induced surface modifications of the polymer. FTIR, XPS, and static contact angle measurements have confirmed the increased surface hydrophobicity of the treated polyimide films.
- Surface Plasmon-Based Techniques for the Analysis of Plasma Deposited Functional Films and Surfaces
Li-Qiang Chu, Qian Zhang and Renate Förch
Article first published online: 17 FEB 2015 | DOI: 10.1002/ppap.201400240
This paper aims to summarize and discuss the application of both SPR and OWS techniques for the characterization of plasma deposited polymers over the past decade. The fundamentals and the implementation of SPR/OWS are given firstly. Examples about the use of SPR/OWS for the analysis of plasma deposited thin films and surfaces are then presented.
