  1. Determination of the Electron Density in an Argon Plasma Jet Using Absolute Measurements of Continuum Radiation

    Leila Taghizadeh, Joost van der Mullen, Anton Nikiforov and Christophe Leys

    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.

  2. 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.

  3. 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.

  4. 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.

  5. Synthesis of Copper Particles by Non-thermal Atmospheric Pressure Plasma Jet

    Andrada Lazea-Stoyanova, Angela Vlad, Aurel Mihai Vlaicu, Valentin Serban Teodorescu and Gheorghe Dinescu

    Article first published online: 16 FEB 2015 | DOI: 10.1002/ppap.201400197

    The study presents the growth of metal particles at atmospheric pressure using a cold radiofrequency plasma jet. The deposition, obtained by the plasma jet, uses as solid precursor the electrode copper material. Copper particles of nano-metric and micro-metric size, which do not tend to agglomerate and do not stick on the substrate are fabricated.
