Abstract:

This thesis encloses quantum chemical calculations and applications of a response function formalism recently implemented within the framework of density functional theory. The optical and magnetic properties of copper(II) molecular systems are the main goal of this work. In this work, the visible and near-infrared electronic transitions, which have shown a key role in studies on electronic structure and structure-function relationships of copper compounds, were investigated in order to explore the correlation of the positions and intensities of these transitions with the geometrical structure

Abstract:

Atomically thin group-VI transition metal dichalcogenides (TMDC) has been emerging as a family of intrinsic 2-dimensional (2D) crystals with a sizeable bandgap in the visible and near infrared range, satisfying numerous requirements for ultimate electronics and optoelectronics. This intrinsic 2D crystal also provides a perfect platform for physics study in 2D semiconductors. The characteristic inversion symmetry breaking presented in monolayer TMDCs leads to non-zero but contrasting Berry curvatures and orbital magnetic moments at K/K’ valleys located at the corners of the first Brillouin zone

Abstract:

It is of fundamental significance to differentiate an enantiomer from its mirror image (i.e., enantiodifferentiation), through monitoring optical activity (OA) of enantiomers that is typically characterized by electronic circular dichroism (ECD or CD) in the UV-visible region. However, sub-wavelength molecular dimensions substantially prevent enantiomers from effectively perceiving the different circular polarization states, leading to low enantiomeric OA and weak enantiodifferentiation. Some approaches have been developed to amplify the enantiomeric OA; alternatively, on the basis of the emer

Abstract:

The optical properties of InAs/GaSb heterostructures under applied magnetic fields are studied in experimental and theoretical detail. The InAs/GaSb system is a type-II "crossed-gap" system, where the valence band edge of GaSb lies higher in energy than the conduction band edge of InAs. This leads to a region of energy above the InAs conduction band where conduction and hole states mix. Thin-layer superlattices remain semiconducting due to confinement effects, but thick-layer superlattices experience charge transfer which leads to intrinsic carrier densities approaching 10<sup>12</sup> cm<sup>

Abstract:

Dans cette these, nous avons etudie les proprietes optiques non lineaires de troisieme ordre de la molecule et du cristal de 4-(n,n diethylamino)-nitrostyrene (deanst). Nous avons fait des mesures d'absorption a deux photons de la molecule de deanst en solution par ellipsometrie kerr. Nous avons modelise le spectre non lineaire ainsi obtenu a partir du spectre d'absorption lineaire et d'un unique parametre: la variation de moment dipolaire entre les etats s#0 et s#1. Nous avons monte un banc z scan qui permet la mesure de l'indice de refraction dependant de l'intensite et de l'absorption non l

Abstract:

Les applications des lasers susceptibles d'emettre a temperature ambiante dans la zone de securite oculaire autour de 1550 et 2000 nm sont tres nombreuses: telemetrie, altimetrie, anemometrie. . . L'obtention de ces lasers peut etre realisee par le dopage de matrices transparentes par les ions terres rares er#3#+, tm#3#+ et ho#3#+. Ceux-ci presentent respectivement une transition radiative vers 1550, 2000 et 2100 nm. Cependant les interactions entre ces ions conduisent a des mecanismes qui diminuent les rendements laser dans l'infrarouge. L'objet de cette these est de decouvrir de nouvelles ma

Abstract:

Differentes methodes de calcul des proprietes optiques des couches minces optiques a profil d'indice continu sont presentees. Dans le cas des filtres rugates, l'utilisation de methodes analytiques a notamment permis un calcul des enveloppes des spectres ainsi que l'optimisation du profil d'indice. Un nouveau systeme de coevaporation sous vide a ete developpe pour realiser des filtres a profil d'indice continu. Des couches minces homogenes de zns, znse, mgf#2, ainsi que de zns-mgf#2 et de znfe-mgf#2 de differentes compositions ont ete realisees. Il apparait que le zns presente un probleme de co
