Texte intégralThis thesis investigates the charge and spin transport processes in 0D, 2D nanostructures and 2D-0D Van der Waals heterostructures (VdWh). The La0.67Sr0.33MnO3 perovskite nanocrystals reveal exceptional magnetoresistances (MR) at low temperature driven by their paramagnetic shell magnetization independently of their ferromagnetic core. A detailed study of MoSe2 field effect transistors enables to elucidate a complete map of the charge injection mechanisms at the metal/MoSe2 interface. An alternative approach is reported for fabricating 2D-0D VdWh suitable for single electron electronics involving the growth of self-assembled Al nanoclusters over the graphene and MoS2 surfaces. The transparency the 2D materials to the vertical electric field enables efficient modulation of the electric state of the supported Al clusters resulting to single electron logic functionalities. The devices consisting of graphene exhibit MR attributed to the magneto-Coulomb effect

Texte intégralThe main objective of this study was to carry the one step synthesis of metal/oxide heterostructures combining microwave and UV irradiation. During this work, we prepared nanoparticles of high industrial potential oxides (CeO2, TiO2 and SnO2) with a precise control of the size and morphology. Isotropic particles and nanorods of CeO2 were first synthetized. Then, a large variety of anatase and rutile nanoparticles, with specific crystalline faces were obtained. Syntheses of SnO2 were finally developed, without or with HCl, to obtain isotropic and elongated nanoparticles respectively. To understand the fundamental difference between formation mechanisms of SnO2, we performed an in situ study, in our microwave apparatus, combining small angle X-ray scattering and X-ray absorption spectroscopy. We were able to give new insights on the formation of these nanoparticles in aqueous solutions. We developed then the first microwave assisted continuous flow synthesis of SnO2 to produce significant amount of materials. Finally, we used the synthetized TiO2 nanoparticles as support to prepare gold catalysts with two different methods: the deposition-precipitation with urea (DPU) and the photodeposition. DPU provided as active nanocatalysts as equivalent catalysts prepared with commercial TiO2. We highlighted a potential impact of crystalline faces of the support. Finally, the photodeposition method led to similar supported gold nanoparticles size range as the DPU. We proposed preliminaries conclusions on the mechanism of the photodeposition

We synthesize copper/zinc oxide heterostructures (Cu/ZnO) by thermal decomposition methods and separate the nucleation and growth process by hot injection method, and then obtaining the nanoparticles with the almost same size. We work on the influence of different reaction temperature and the type of injection. By controlling both of the factors, we can synthesize highly crystalline heterostructures with copper nanoparticles of forty nanometers and the zinc oxide shell of the thickness of four nanometers. We transfer Cu/ZnO into water phase, and alloy to the photocatalttic reaction. We are based on the done work of the synthesis of gold/cadmium selenide heterostructures, analyzing further the shell structure. We use cadmium nitrate and sodium borohydride to control the CdSe shell thickness, and analyze the absorption values and measure the photoluminescence signal. In addition we measure two-photon luminescence imaging as well as the photocatalytic reaction. We use TOP and oleylamine to reduce copper chloride at high temperature. By tuning the concentration of copper chloride and the reaction time to prepare copper nanocrystals with morphology evolution.We observe X-ray diffraction patterns to analyze the crystalline structure, and observe absorption values to determine optical properties. Analyzing SEM images and TEM images to Analyze the surface morphology and the rationality of its evolution.
