Full textThis thesis presents research work on self-organized metal-organic monolayers. We have theoretically investigated the structural, electronic and magnetic properties of two-dimensional TM-Pc (Pc: phthalocyanine) and TM-TCNB (TCNB: tetracyanobenzene) where TM is the transition metal for the 3d, 4d or 5d series. The calculations are performed by density functional theory taking into account the Hubbard term (DFT+U) using the VASP simulation code (Vienna Ab-initio Simulation Package). In addition, the adsorption of the Fe-Pc molecule on the gold surface Au(111) was studied via SGGA and SGGA+U

Full text(The NaxCoO2 Cobalt oxides are compounds with many interesting properties. In this work we were particularly interested in two compounds of the family: firstly, the Na0. 3CoO2-1. 3H2O which presents a superconducting phase, secondly the x=0. 5 system which presents an insulator to metal phase transition at 52 K and a rich phase diagram as a function of temperature and magnetic field. Using ab initio calculations molecular spectroscopy methods applied on fragments embedded in an appropriate bath, we presented the determination of simple models as well as the evaluation of the effective interactions for these two interesting compounds. We also studied the cobalt 3d-shell splitting under the trigonal distortion observed in these compounds. This analysis led to reasons for which some results, like the ones issued of ligands field theory and some issued of density functional calculations, yield an orbital splitting in disagreement with experimental results

Full textLayered cobalt oxides compounds are built from CoO2 layers intercalated either by Na or Ni layers or by more complex structures. First studied for their high ionic conductivity, their interest was revived by the discovery of properties such as the supraconductivity in NaxCoO2 hydrated phases, puzzling magnetic phases and high thermoelectric power. In our work, we aimed at the determination of the fermi-level electrons degrees of freedom, responsible for the low energy physical properties, on three layered cobalt oxides : [Ca2CoO3]0. 62[CoO2], Na2/3CoO2 and CoO2. To reach this goal, wave function ab-initio calculations, taking correctly into account the strong electronic correlation, have been performed on fragments of the studied compounds. Local effective interactions between Femi-level electrons were determined and exchange coupling or Hubbard model parameters were evaluated

Full textOur research concerns the theoretical study of the electronic structure of diatomic molecules such as Aluminum mono-halides AlX (X = Br,I) and Lutetium mono-halides LuX (X = F, Cl). The ab-initio methods are used for our study. These methods SCF, CASSCF (Complete Active-Space Self-Consistent Field) and interaction of configuration multi-reference MRCI with and without Davidson correction. These calculations are performed using the quantum chemistry software package MOLPRO, benefiting from the use of graphic interface GABEDIT. Our findings have consolidated the potential energy curves PECs, spectroscopic constants, including harmonic frequency ωe(cm-1), the internuclear distance at equilibrium Re(Å) and energy Te(cm-1) for a set of singlet and triplet electronic states in the representation 2s +1 Λ (+/-) (neglecting spin-orbit effects) for these four molecules. By comparison between our results and those contributed to the literature, we found a good agreement with a low percentage of error does not exceed 3% from the experimental value was considered as exact

Full textThis work is about the theoretical study of several systems and some of their dynamical processes. First, we have applied different electronic structure calculation methods to the structural study of glass systems made of gallium, lanthanum and sulfur, whose physical properties have been observed to be improved by cesium chloride doping. We have confirmed that previously obtained experimental results are insufficient to explain this changes and that these studies must be completed by additional experiments. Particularly, our calculations have shown that pertinent informations could be obtained by studying these glasses by vibrational spectroscopy. Second, we have studied the compound Ag2V4O11 (SVO) by means of the Density Functional Theory (DFT). This compound is largely used as electrode material for lithium batteries. We have obtained results partly clarifying a controversy relative to the crystal structure of SVO, for which three different structures have been reported. We have then made an ab initio molecular dynamics study of the mobility of metallic ions in this system. Our results give useful informations for the understanding of the complex mechanism of lithium insertion on SVO. Lastly, we have studied a case of a system which is not under the Born-Oppenheimer approximation. We have simulated the tunneling process of a quantum particle evolving in a metastable potential well, and we have estimated its tunneling time, by means of an original semiclassical molecular dynamics method. The use of these ab initio calculation methods for the study of these three different cases has allowed us to evaluate their capacity to elucidate electronic structure problems and to describe physical-chemical phenomena existing in complex systems
