We report the successful formation of bulk insulating ternary topological insulators candidate Bi2Se2Te (BST) by pulsed laser deposition technique. The films were deposited with sequential ablation of separate Bi2Se3 (BS) and Bi2Te3 (BT) targets. From the X-ray diffraction analysis and temperature dependent resistivit…
A new Laves phase superconductor NbBe2, prototype with MgCu2, having maximum Tc ~2.6 K has been reported very recently. Based on first-principle calculations, we systematically study the structural, elastic, mechanical, electronic, thermal and superconducting properties of the newly reported superconducting intermetal…
Flexible electronic devices require the integration of multiple crucial components on soft substrates to achieve their functions. In particular, memory devices are the fundamental component for data storage and processing in flexible electronics. Here, we present flexible MgO barrier magnetic tunnel junction (MTJ) dev…
Recent advances in experimental and computational techniques have allowed for an accurate description of the adsorption of ionic liquids on metallic electrodes. It is now well established that they adopt a multi-layered structure, and that the composition of the layers changes with the potential of the electrode. In s…
Strontium ferrite nanoparticles were prepared by a coprecipitation method, and reduced graphene oxide/strontium ferrite/polyaniline (R-GO/SF/PANI) ternary nanocomposites were prepared by in situ polymerization method. The morphology, structure, and magnetic properties of the ternary nanocomposites were investigated by…
Recently, phosphorene electronic and optoelectronic prototype devices have been fabricated with various metal electrodes. We systematically explore for the first time the contact properties of monolayer (ML) phosphorene with a series of commonly used metals in a transistor by using both ab initio electronic structure…
Subseries contains two boxes of microfilm which are copies of the papers found in this subseries.
Ces travaux de recherche portent sur la conception et la réalisation de commutateurs RF basées sur l’intégration de matériaux innovants fonctionnels tels que le dioxyde de vanadium (VO2) et les alliages de chalcogénures de types Ge2Sb2Te5 (GST) et GeTe. Le principe de fonctionnement de ces composants repose sur le cha…
Nucléation non-photochimique induite par laser (NPLIN) : Contribution au mécanisme de nucléation à travers des études expérimentales sur le sulfathiazole, L-acide glutamique et la glycine et la modélisation de quelques petites molécules Cette thèse a pour but de démontrer la faisabilité de la technique de Nucléation n…
La micro et la nanotechnologie a créé un bouleversement dans beaucoup de domaine tel que l’industrie ou la recherche. Pour la recherche, les enjeux économiques (quantité) et écologiques (déchets, risques chimiques) vont directement dans le sens de cette miniaturisation pour l’obtention de procédé sûr, propre et moins…
Les alcools gras sont des corps gras cristallisables utilisés dans les produits cosmétiques pour les consistances qu’ils génèrent. Le projet de thèse a pour objectif de contrôler la cristallisation d’alcools gras fondus et dispersés en présence de chlorure de cétyl trimetyl ammonium. L’enjeu est d’identifier l’influen…
Prédiction de la conductivité thermique et stratégie de réduction du transport de la chaleur dans le bismuth : étude ab initio. Cette thèse de doctorat porte sur l'étude théorique de la conductivité thermique du réseau dans le bismuth semi-métallique et sur les stratégies pour réduire la conductivité thermique en vue…

We have developed a method for the three-dimensional (3D) printing of continuous fiber-reinforced thermoplastics based on fused-deposition modeling. The technique enables direct 3D fabrication without the use of molds and may become the standard next-generation composite fabrication methodology. A thermoplastic filame…
Recently, the interest in the renewable energies is increasing after the Great East Japan Earthquake in 2011. A solar cell is one of the renewable energies, and especially a dye−sensitized solar cell is expected for a various applications because of low price, facility of fabrication, and high efficiency in electricit…
The reinvestigation of the pseudo-binary systems MBrBiBr3 (M = Rb, Cs) revealed two new phases with composition MBi2Br7. Both compounds are hygroscopic and show brilliant yellow color. The crystal structures were solved from X-ray single crystal diffraction data. The isostructural compounds adopt a new structure type…
