“…In this context and in view of the material science challenges, plasma techniques appear as an ideal technological platform to synthesize these materials. Indeed, these technologies are known as "green" technologies, since they allow for good control of the material properties and their industrial transfer has been demonstrated in many fields such as the glass industry or microelectronics [17][18][19][20][21]. Among these technologies, magnetron sputtering (MS) is usually used to grow dense thin films of various materials (from metal to polymer coatings) [21][22][23].…”

Today, Mg is foreseen as one of the most promising materials for hydrogen storage when prepared as nano-objects. In this context, we have studied the fabrication of Mg nano-sculpted thin films by magnetron sputtering deposition in glancing angle configuration. It is demonstrated that the microstructure of the material is controllable by tuning important deposition parameters such as the tilt angle or the deposition pressure which both strongly affect the shadowing effect during deposition. As an example, the angle formed by the column and the substrate and the intercolumnar space varies between ~20° to ~50° and ~45 to ~120 nm, respectively, when increasing the tilt angle from 60° to 90°. These observations are highlighted by modeling the growth of the material using kinetic Monte Carlo methods which highlights the role of surface diffusion during the synthesis of the coating. This work is a first step towards the development of an air-stable material for hydrogen storage.

“…Nevertheless, when used in the glancing angle deposition (GLAD) configuration, it has been demonstrated that nanostructurated coatings for the microstructure can be controlled. As an example, we recently reported on the growth of Ti and TiO 2 nanostructurated films by using this approach [19,20].…”

“…TiO 2 is a wide bandgap n‐type semiconductor (~3.0 to 3.2 eV) which is nowadays efficiently used as photoanode in n‐DSSCs due to its high transparency in the near UV‐visible light region . Furthermore, TiO 2 possesses a good chemical affinity to carboxylic acid, which is an easily synthetically accessible anchoring group for many dyes and its specific surface area is easily tunable . In this context, the development of TiO 2 ‐based photocathode would be particularly interesting for large scale production of t‐DSSCs as it would limit the complexity of the deposition systems.…”

Tandem dye‐sensitized solar cell devices (t‐DSSCs) are a potential alternative to Si‐based solar cells as autonomous power sources. Nevertheless, their further development suffers from the poor quality of the p‐type material, that is, NiO. In this study, N‐doped TiO2 thin films exhibiting a p‐type conductivity (p‐TiO2:N) are successfully grown by co‐reactive magnetron sputtering. Its p‐type conductivity is correlated to the incorporation of N atoms in substitutional positions which is controllable by carefully tuning the ratio between O2 and N2 reactive gases during the growth of the material. Furthermore, it reveals a three to six times higher mobility of the carriers (1.5–3.1 cm2·V−1·s−1) than sputtered NiO. These results are in particular interest for the development of new TiO2‐based t‐DSSCs.
