This work reports the electrochemical synthesis of polypyrrole (PPy)films onto silicon (Si) support in an organic solution usingpotentiostatic mode of electrodeposition. Electrodeposition of PPy wasconducted under oxidative conditions; the current transient curve,taken at constant potential of 1.1 V, was discussed. The microstructureof the polypyrrole (PPy) films obtained is examined by SEM andAFM.

The exact solvable model of the Rydberg dressed interaction for twoparticles proposed by Kościk et al. is analyzed in the differentdimensions to single out the impact of the dimensionality. First weanalyze the effect on the energy spectrum then spatial correlations arestudied as the radial density distribution versus the position in the threedimensionalities. The results clarify the effect of the centrifugal forcesin the presence of long range interaction.

Dans ce travail nous avons étudié l’effet du temps de déposition sur lesdifférentes propriétés des couches minces d’oxyde de cuivre. En premierlieu nous avons élaboré des films minces de Cu 2O par électrodéposition surun substrat ITO dans un milieu sulfate à température fixé de T=60° et unpotentiel imposé de - 0.5V/ECS. En second lieu les couches minces del’oxyde de cuivre (Cu 2O/ITO) ont subi un traitement thermique àtempérature de 500 °C pendant 1h pour obtenir des films mince nomméCuO/ITO. Les couches minces déposées ont été caractérisées par ladiffraction du rayon X (DRX), la microscopie à force atomique (AFM), lemicroscope électronique à balayage (MEB) et la spectroscopie UV-Vis.L’activité photocatalytique des films Cu 2O et CuO a été étudiée au moyende la dégradation du méthyl orange (MO) sous irradiation directe de rayonsUV. Les propriétés photocalytique montrent des meilleures vitesses dedégradation avec une constante de vitesse de l’ordre 0,00087 min -1 pourCu2O et 0.0025 min-1 pour CuO.
