Hydrogen plasma etching of diamond films deposited on graphite

Autor: J. I. B. Wilson, I. Villalpando, Samuele Porro, Phillip John

Publikováno v: Diamond and Related Materials. 20:711-716

Poly- and nanocrystalline diamond films have been deposited using microwave plasma enhanced CVD with gas mixtures of x%CH4/15%H2/Ar (x = 0.5, 1, 3, and 5). After deposition the resulting films were exposed to a hydrogen plasma etching for 30 min. The

Spatially resolved atomic excitation temperatures in CH4/H2and C3H8/H2RF discharges by optical emission spectroscopy

Autor: C Thomas, J. I. B. Wilson, T Burinprakhon, A Chingsungnoen, Vittaya Amornkitbamrung

Publikováno v: Plasma Sources Science and Technology. 16:434-440

Spatially resolved optical emission spectroscopy was used to determine the atomic excitation temperature of the capacitively coupled radio-frequency (RF) plasma system. Low pressure plasmas of methane or propane in hydrogen were excited at 13.56 MHz

Parallel adaptive tetrahedral mesh generation by the advancing front technique

Autor: Barry Hilary Valentine Topping, J I B Wilson

Publikováno v: Computers & Structures. 68:57-78

A parallel adaptive tetrahedral mesh generation program using the advancing front method is described. The problem domain is initially defined by a course background mesh of tetrahedral elements which forms the input for finite element analysis and f

Diamond coatings exposure to fusion-relevant plasma conditions

Autor: D.L. Rudakov, Phillip John, Andrey Litnovsky, Per Petersson, S.W. Lisgo, Samuele Porro, J. I. B. Wilson, G. De Temmerman

Publikováno v: Journal of Nuclear Materials, 415, S161-S164

Several types of diamond layers have been deposited on molybdenum tiles by chemical vapour deposition techniques, and exposed under erosion-dominated conditions in the SOL of TEXTOR in order to assess them as a suitable candidate for plasma-facing ma

Nanocrystalline diamond coating of fusion plasma facing components

Autor: Bob Johnson, Samuele Porro, Jerry W. Zimmer, Gregory De Temmerman, Phillip John, S. Lisgo, I. Villalpando, J. I. B. Wilson

Nanocrystalline diamond layers were deposited by hot-filament CVD on several substrates including molybdenum tiles and foils, graphite blocks and silicon wafers. The structural characterisation of the deposited layers, achieved by SEM, AFM, Raman and

Publikováno v: International Journal of Material Forming. 1

Effective light trapping is essential for the conversion efficiency increase in thin film solar cells. Vertically aligned multiwalled carbon nanotubes (MWNTs) arrays with proper spacing form an ideal light trapping structure. In this work, we have de

Publikováno v: Optics Express. 15:12619

Light induced dielectrophoresis (LIDEP) is a variant of the dielectrophoresis (DEP) mechanism that has been used for some time to manipulate particles in a microfluidic environment. Rather than relying on lithographically created contacts to generate
