Ultra-thin WS2 growth by ALD from bis(tert-butylimido)bis(dimethylamido)tungsten and 1,2-ethanedithiol and detailed surface mechanism

Zakaria Qoraiche, Medet Zhukush, Jules Galipaud, Laurent Veyre et autres

A molecular layer deposition/atomic layer deposition (MLD/ALD) strategy using bis(tert-butylimido)bis(dimethylamido)tungsten (BTBMW) and 1,2-ethanedithiol (EDT), the latter serving as a safer organic alternative to H2S, leads to the formation of ultrathin WS2 films via a molecular/hybrid tungsten organothiolate intermediate. A multiscale approach, involving …

Role of chemistry changes in the hydrophobic transition following femtosecond laser texturing of stainless steel

Laora Lamour, C. Minfray, Jules Galipaud, S. Valette

Hydrophobicity is a targeted surface property in many industries due to the variety of functionalities (anti-corrosion, antibacterial, anti-icing, etc.) it enables. Femtosecond laser, as part of the ultra-short pulsed laser category, can be used to design such surfaces. After the texturing process, …

Reactions of Bis(tert‑butylimino)bis(dimethylamino) Tungsten(VI) with molecular silanol, silica and silicon wafer : Analogy Between Molecular and Surface Chemistries relevant to ALD thin film growths from BTBMW

Zakaria Qoraiche, Medet Zhukush, Jules Galipaud, Clément Camp et autres

We investigate the very first stages of tungsten film growth by atomic layer deposition (ALD) using the W(VI) precursor bis(t‑butylimino)bis(dimethylamino)tungsten BTBMW. Attention is given to the initial metal precursor pulse, probed on both model silica nanobeads support and SiO2-terminated silicon wafers. To …

Corrosion fatigue mechanisms of high-strength steel wires in the presence of various aggressive ions

Jonathan Quibel, Nicolas Mary, Jules Galipaud, Marion Frégonèse et autres

This work focuses on the corrosion fatigue of high-strength steel wires with diameters of 200 μm. The fatigue load consists of a bending rotation with a stress amplitude between 1300 MPa and 700 MPa. Various solutions at pH 6 containing either sulfate, …

Role of Ce 4f States in the Electronic Structure and Photoelectrochemical Activity of Brannerite CeTi 2 O 6– X

Cyril Hachemi, Mourad Debbichi, Jules Galipaud, Adel Mesbah et autres

Cerium has been proposed as an attractive element in photoconversion systems, but the role of the Ce 3+ /Ce 4+ redox couple in light-driven processes remains a subject of debate due to the localized nature of Ce 4f electrons. Moreover, in state-of-the-art …
