Force field parameters are taken from a previous work. These simulations allow for atomic scale insights into the deposition mechanisms and an easier comparison with experimental observations. The results, including distributions of implantation depth, carbon concentrations, sticking coefficients, radial distribution function, and angular distributions are compared for different incidence angles. Due to the deposition of carbon atoms inside the silicon structure, silicon carbide starts to form. The crystalline structure has been investigated for different conditions to get a better understanding of the damaging and growth mechanisms. It is found that a lot of deformation is accumulated in the area of deposition near to the surface but underneath the surface the silicon has still a more crystalline structure. The variation of the silicon (carbide) structu re slightly depends on the angle of incidence. For the conditions used for these simulations, the sticking probability is always high and varies between 95% and 100%, which can be attributed to the high affinity of carbon for silicon.

Aida N.Attaf T.Bezzi J.Bougdira G.Medjahdi article 201-4342 Journal of Physics D: Applied Physics 2014 47 205201 The electron temperature and electron density are measured in a microwave (MW) plasma-assisted chemical vapour diamond deposition reactor for different experimental conditions by varying the substrate temperature, methane content and MW power density. Optical emission spectroscopy (OES) and MW interferometry are used to probe the discharge generated in a stainless steel resonant cavity excited at a frequency of 2.45 GHz. Changing the substrate temperature from 630 to 900 ◦C does not show any significant influence on the electron temperature or on the electron density. Increasing the methane content from 0 to 10% does not lead to any modification of the electron temperature or density. However between 10% and 20% CH, a decrease of the electron density is observed which may be attributed to soot particle formation. The electron density increases in the range of (1.2–10) × 1011 cm−3 from moderate power density conditions (50 hPa/1000 W) to high power density conditions (250 hPa/3500 W). OES measurements show that the electron temperature exhibits a flat axial profile in the plasma bulk and ranges from 14 000K at (25 hPa/600 W) to 10 500K at (400 hPa/3000 W).

The plasma is characterized by OES and imaged using an EMCCD camera. The effect of hydrogen admixture to the formed structures is studied by transmission electron microscopy. Under specific conditions, crystalline silicon nanoparticles grow in an amorphous matrix investigated by electron energy loss spectroscopy. As-grown silicon nanoparticles are collected in ethanol for dynamic light scattering and photoluminescence measurements. The size distribution peaks at 4 nm. The silicon nanocrystals exhibit roomtemperature photoluminescence that peaks at ~415 and ~465 nm Département CP2S : ESPRITS 10.1002/ppap.201400047 B.Barwe A.Stein O.E.

The present study reports on experimental results on the ageing of a usual PEO electrolyte and its effect on the oxidation of the Al2214 aluminium alloy. A solution of potassium hydroxide ([KOH] = 1 g/L) and sodium silicate ([Na2SiO3] = 1.65 g/L) diluted in deionized water was either aged by running a process during 8 h at most or not. Comparison between materials treated in either solution was made next. Cross-checked experimental results from analytical chemistry, plasma diagnostics and materials science clearly evidence the effect of ageing of the electrolyte on the PEO process behaviour. The transition from arc to "soft" regime occurs earlier (from 18 min to 13 min processing time) as the electrolyte gets older. The concomitant decrease in the electrolyte electrical conductivity (from 7.5 mS.cm-1 to 6.8 mS.cm-1) is correlated with changes in the ionic species content in the electrolyte. Fast video-imaging (125 kfr./s) reveals that the micro-discharge characteristics are also sensitive since they become less numerous per area and unit time (from 220.103 cm-2s-1 to 120.103 cm-2s-1), exhibit shorter lifetime and have smaller sizes as the electrolyte ages. SEM observations of the as-grown coatings combined with roughness measures indicate a decrease in coating thickness ( ~ 20 %) and roughness ( ~ 30 %) while species from the electrolyte accumulate in the outer porous layer simultaneously with a gradual enrichment in a-Al2O3 phase in the inner compact layer (from 36 % to 43 %). Finally, within the PEO conditions that were used, it is shown that the ageing phenomenon of the PEO electrolyte starts to influence the process after 2 hours aged.

In this work, the initial stagesof anodic layer growth in KOH-based electrolytes are studied up to and beyond the initiation of themicro-arc regime.The properties of the first anodized film preceding the occurrence of the dielectric breakdown (corre-sponding to the start of the micro-arc regime) are mainly determined by the incorporation of additives(fluorides or silicates) in the film, as shown by in situ electrochemical measurements. Scanning electronmicroscopy (SEM), X-ray photoelectron spectroscopy (XPS) and micro-Raman spectroscopy reveal boththe change of morphology and chemical state of silicate and fluoride in the anodized layer before andafter the micro-arc regime. In terms of electrochemical behaviour, investigated by stationary methodsand electrochemical impedance spectroscopy (EIS) in reference corrosive water, the anodic film grownin the silicate medium provides the best corrosion resistance thanks to a thick layer containing Mg2SiO4,whose degradation products seal the porosities of the coating.

Unusual PEO cathodic microdischarges have been observed and investigated. It is shown that the cathodic micro-discharges exhibit a collective intermittent behavior, which is discussed in terms of charge accumulations at the layer/electrolyte and layer/metal interfaces. Optical emission spectroscopy is used to determine the electron density (typ. 1015cm_3) and the electron temperature (typ. 7500K) while the role of F_ anions on the appearance of cathodic micro-discharges is pointed out.
