Texto completo da fonteDuring this work, we have investigated, using DFT calculation and topological analysis of the electron density, the metal to insulator phase transition occuring in the organic compound (EDO-TTF)2PF6. This phase transition takes place at 278K but can also be photo-induced on pico-second time scale. It also exhibits many different aspects of phase transition : Peierls like instability, exotic 0 +1 +1 0 charge ordering of EDO-TTF tetramers and orientational ordering of PF6 ions. Using high and low temperature band structure as well as bond critical points analysis we could fit a tight-binding model to ab-initio calculations from which we have been able to find and characterize the charge density wave and propose a transition mechanism governed by coulombic interactions

Texto completo da fonteTo analyze the improvements in electronic properties of carbon-based materials, an approach based on the density functional theory supported by Raman spectroscopy was used. The heart of this work is the study of doping in order to open up new paths for the design of innovative materials from nanodevices. These new structures are fibers whose the main component is a carbon nanotube or nanocarbon loaded polymers with molecules, optimizing electrical conduction. A brief introduction is presented on non-covalent species, leading to the best results reported in the literature, namely potassium, iodine and super acids. The graphite intercalation compounds by potassium atoms are analyzed first. The large charge transfer of the alkali directly influences the optical properties of graphene, resulting in a unique Raman signature with a shape change when the excitation energy is twice the shift of the Fermi level due to doping. Then, an exhaustive theoretical study of iodine doping is performed on a monolayer of graphene. Analysis of thermodynamic properties shows that a gradual increase in the recovery rate of the molecules, initially generates a phase transition of iodine adsorption mode, and ends with the formation of polyiodide complexes. These complexes, via a strong electron transfer, lead to the increase of the density of states at the Fermi level. This study is extended to carbon nanotubes, where a very large charge transfer is obtained after interacting either with chlorosulfonic acid molecules by redox reaction, or with iodine molecules. When there is a flow of a large electric current in these fibers, the Joule effect produces a desorption of dopants and reduces the electrical conductivity. This phenomenon is explained by the available number of conduction channels deducted from combined Raman signatures and electronic transport calculations. The local and average temperatures are extracted from Raman and transport data respectively. This work constitutes a coherent set of results as a basis for improving the transport properties

Texto completo da fonteThis work describes a general study of the layered compounds AMX2 (A = Li, Na ; M = Transition Metals; X = O, S, Se) usually used as positive electrode in the rechargeable batteries. First principal calculations are used to investigate the structural, electronic and electrochemical properties of theses compounds. The open circuit voltage variation is correlated to the nature of the alkali, the transition metal and the chalcogene. The results are interpreted with the charge transfer phenomena. It has been shown that the behaviour with the lithium intercalation is different from sodium intercalation. So, the understanding of the charge transfer is the key criteria to obtain a high potential
Sayede, Adlane D. "Étude du comportement structural, électronique, catalytique et électrochimique des oxydes d'intercalation (V2O5, MoO3, WO3 et ReO3) par des méthodes du premier principe". Artois, 2003. http://www.theses.fr/2003ARTO0404.
Texto completo da fonteThis work concerns the determination of the structural, electronic, catalytic and electrochemical properties of a class of intercalation oxides (the pentoxyde of vanadium (V2O5), the trioxyde of molybdenum (MoO3), the trioxyde of tungsten (WO3) and the trioxyde of rhenium (ReO3)). In this goal we have used two first principle calculation methods : the Hartree-Fock (HF) method and the linear augmented planes wave (LAPW) method. These two methods allowed us to optimize the results relative to every studied property. The studied have an ionocovalent character on the bulk and surface level. Surface oxygens of V2O5 and MoO3 behave as species chemically distinct so offering an interesting catalytic activity. The adsorption of the hydrogens for example preferably takes place on molybdenyls oxygens on the surface (100) of alpha-MoO3. The effect of the insertion of the lithium on the surface of V2O5 was approached and shown that lithium ions yield its charge to the surface, which gives slightly modified electronic and structural properties. Intercalation of alkaline such lithium, sodium and potassium in ReO3 type oxides shows a modification of the structural, electronic and electrochemical properties of these oxides
