TL;DR: In this article, undoped and nitrogen doped TiO2 thin films were deposited by atomic layer deposition on planar planar substrates, resulting in films exhibiting a resistivity of 115 Omega cm (+/-10 Omega cm) combined with an average total transmittance of 60% in the 400-1000 nm wavelength range.
Journal ArticleDOI
Study of 3C-SiC nucleation on (0 0 0 1) 6H-SiC nominal surfaces by the CF-PVT method
Laurence Latu-Romain,Didier Chaussende,Patrick Chaudouët,F. Robaut,G. Berthomé,Michel Pons,Roland Madar +6 more
TL;DR: In this paper, 3C-SiC nucleation on nominal surfaces was investigated during the heating-up step of the continuous feed-physical vapour transport (CF-PVT) growth technique, and the 3C proportion reached a maximum for a well defined temperature which was higher on the C face than on the Si face.
Journal ArticleDOI
Microstructures of titanium oxide thin films grown continuously on stainless steel wires by PVD in an inverted cylindrical magnetron: Towards an industrial process
C. Esparza-Contro,G. Berthomé,Gilles Renou,F. Robaut,Stéphane Coindeau,C. Vachey,J. Cambin,Marc Mantel,Laurence Latu-Romain +8 more
TL;DR: In this paper, the microstructure of TiOx thin films is analyzed as a function of the O2 flux in the chamber, and a 300-nm polycrystalline hexagonal Ti film is obtained in 2min 30s at 1000 W.
Journal ArticleDOI
Aluminum nitride homoepitaxial growth on polar and non-polar AlN PVT substrates by high temperature CVD (HTCVD).
A. Claudel,Yann Chowanek,Elisabeth Blanquet,Didier Chaussende,Raphaël Boichot,Alexandre Crisci,G. Berthomé,Hugues Mank,Sorana Luca,D. Pique,Michel Pons +10 more
TL;DR: In this article, the homoepitaxial growth of aluminum nitride on polar and non-polar AlN PVT seeds by HVPE or HTCVD is studied.
Journal ArticleDOI
Thickness effects in naturally superhydrophilic TiO2–SiO2 nanocomposite films deposited via a multilayer sol–gel route
TL;DR: In this paper, the photo-induced wettability of composite nanocomposite films was studied and discussed in relation to morphology, composition, and thickness features, and it was concluded that while such features did not significantly influence the natural wettable of nanocomposition films, their photo-induced wetability was considerably enhanced when increasing their thickness, which favored a faster superhydrophilicity photo-regeneration when this natural property started to disappear after a long aging period.
