Повний текст джерелаThe optical control of the physical properties of a material has drawn considerable attention during the past few years for a fundamental point of view and for applications. The originality of the project developed during this thesis was based on the synthesis and the study of photo-magnetic heterostructures in a temperature range convenient for applications. The approach consisted of developing multiferroic-like heterostructures that associate a piezomagnetic phase and a photo-strictive phase. The idea was to exploit the coupling of elastic origin between these properties, to allow the observation of photo-magnetic effects at temperatures higher than those reported for single-phase materials. The photo-strictive phase can deform under light irradiation, generating biaxial strain in the magnetic phase. If the piezomagnetic response of the latter is high enough, its magnetization could be modulated, especially at the vicinity of the Curie temperature, with a possible shift of the critical temperature under stress. In this project, we focused on molecular solids based on polycyanometallates, namely Prussian blue analogues, whose generic formula is AxM[M’(CN)6]y . zH2O (where A is an alkali metal and M,M transition metals). We used the compound Rb0,5Co[Fe(CN)6]0,8 . zH2O for the photo-strictive phase and Rb0,2Ni[Cr(CN)6]0,7 . z’H2O or K0,2Ni[Cr(CN)6]0,7 . z’H2O for the magnetic phase. These two phases have a lattice mismatch of 5.3%The main objective of this work was to understand and to control the elastic coupling between the core and the shell. We first highlighted the existence of this coupling, the presence of the shell changing the photo-switching properties of the core, and the deformation of the crystalline lattice of the core inducing structural and magnetic modifications in the shell. Then, we focused on the study of different parameters which can have an impact on the behavior of the heterostructures under light irradiation. We showed that the volumic ratio between the core and the shell is a key factor to control the efficiency of the coupling. The microstructure of the shell can also play an important role, but is not as well understood. In the end, we studied other Prussian blue analogs shells in order to change the lattice mismatch between the core and the shell. We could evidence that by reducing the lattice mismatch we tend to increase the coupling, but if this coupling is to strong, the retroaction of the shell hinders completely the dilatation of the core lattice. The idea is also to find a compromise between the strength of the coupling and the strength of the shell retroaction. In the end, we proved that we cannot associate the effect of the shell to an hydrostatic pressure, but that the coupling of the crystalline lattices play an important role in the synergy between the two phases

Повний текст джерелаOver the past decade, the development of novel nanostructured architectures has raised increasing interest within the scientific community in order to meet the demand for low-cost and efficient functional devices composed of abundant and non-toxic materials. A promising path is to use ZnO nanowires grown by chemical bath deposition as building blocks for these next generation functional devices. However, the precise control of the ZnO nanowires structural uniformity and the investigation of their physical properties, particularly in terms of polarity, remain key technological challenges for their efficient integration into functional devices.During this PhD, the chemical bath deposition of ZnO nanowires is combined with electron beam lithography prepared ZnO single crystal substrates of O- and Zn-polarity following the selective area growth approach. The significant effects of polarity on the growth mechanism of ZnO nanowires, as well as on their electrical and optical properties, are highlighted by precisely investigating the resulting well-ordered O- and Zn-polar ZnO nanowire arrays. An alternative nano-imprint lithography technique is subsequently used to grow well-ordered ZnO nanowire arrays over large areas on various polycrystalline ZnO seed layers, thus paving the way for their future integration into devices. We also demonstrate the possibility to form ZnO nanowires by chemical bath deposition on original semipolar ZnO single crystal substrates. These findings allowed a comprehensive understanding of the nucleation and growth mechanisms of ZnO nanowires on polycrystalline ZnO seed layers.In a device perspective, the ZnO nanowires are subsequently combined with p type semiconducting shells by liquid and vapor chemical deposition techniques to form original core-shell heterostructures. The formation of a cubic phase SnS absorbing shell is optimized by the successive ionic layer adsorption and reaction (SILAR) process on ZnO nanowire arrays coated with a thin protective TiO2 shell, which pave the way for their integration into extremely thin absorber solar cells. A self-powered UV photo-detector with fast response and state of the art performances is also achieved by the chemical vapor deposition of a CuCrO2 shell on ZnO nanowire arrays

Повний текст джерелаThis 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

The formation of heterostrucure in nanorods is essential for their potential applications in nanoelectronic and photonic devices. Here we demonstrate that vertically well-aligned ZnO nanorods and ZnO/MgZnO core-shell nanorods can be successfully synthesized via catalyst-free vapor phase transport combined with pulsed laser deposition (PLD) method. The thesis consists of two parts. First, the vertically well-aligned ZnO nanorods were grown on a PLD-predeposited ZnO thin film via a simple thermal evaporation and vapor transport process. These ZnO nanorods were quite uniform with a diameter of ~27 nm and length of ~1 μm. Room-temperature photoluminescence spectra of the samples showed only a strong band-edge emission, indicating the high crystalline quality. The well-aligned ZnO nanorods were used as a template for the synthesis of nanorod heterostructures. In the second part, the vertically well-aligned ZnO/MgZnO core-shell structures of the nanorods were synthesized by PLD of MgZnO onto the ZnO nanorod template. The core-shell heterostructure nanorods were examined by high-resolution transmission electron microscopy measurements. The optical properties of the heterostructure nanorods were analyzed by photoluminescence. The HRTEM images and the corresponding FFT patterns of the nanorods implied that the core/shell is wurtzite structured ZnO/MgZnO with well-defined epitaxial relationship. The positions of the MgxZn1-xO shells, obtained by pused laser ablating MgyZn1-yO targets with y=0.0909 and 0.25, were determained by the Vegard’s law to be x=0.14 and 0.30, respectively. Room-temperature PL spectrum from the ZnO/MgxZn1-xO core-shell nanorods exhibits strong emissions from ZnO core (located at 3.298eV) and MgxZn1-xO shell (located at 3.539eV for x=0.14 and 3.935eV for x=0.30). The core/shell relative emission intensity can be controlled by the shell thickness.
