Quantum properties of spherical semiconductor quantum dots
Quantum effects at the nanometric level have been observed in many confined structures, and particularly in semiconductor quantum dots (QDs). In this work, we propose... -
Propriétés excitoniques de puits quantiques ZnO/(Zn,Mg)O
Zinc oxide is a wide gap semiconductor (≈ 3.4 eV) which one of the main advantages is a large exciton binding energy (60 meV). This thesis is dedicated to the study of... -

Local wavefunctions in the tight-binding theory
The energy band interpolation is a well known problem in solid state theory. It is often disconnected from the consideration of wavefunctions, in particular in the... -
Coherent manipulation under resonant excitation of a single quantum dot state
The aim of this thesis was to highlight the possibility of using semiconductor quantum dots as the realization of quantum bits, building blocks of quantum information.... -
Solitons, half-solitons and vortex lattices in a polariton fluid
This work is devoted to the study of polariton quantum fluids in semiconductor microcavities and in particular to the generation of solitons, half-solitons and vortex... -
Modelling ultrafast exciton transfer in fluorene-based organic semiconductors
