Persistent currents in a ring threated by a magnetic flux is one of the most basic properties of mesoscopic physics. In the presence of a magnetic flux, a mesoscopic...

This thesis investigates experimental characterisation and understanding of InAs/InP(311)B quantum dots media for laser and SOA applications at 1,55 µm. In the first...

Les composants semiconducteurs de puissance sont depuis toujours à la base des développements des convertisseurs statiques. Le rôle d'interrupteur qu'ils jouent,...

In this thesis manuscript, we present a theory describing the coupling between the quantized electromagnetic field of a cavity resonator and the cyclotron transition...

This thesis presents an experimental and theoretical study of the acoustic phonon dynamics at the nanometric scale, by picosecond acoustic techniques and Raman...

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...

This work reports on electronic design, epitaxial growth and characterization of GaN/Al(Ga)N quantum wells which constitute the active region of intersubband (ISB)...

Zinc oxide (ZnO) is a II-VI semiconductor which appears as a very promising material for UV opto-electronic applications, in particular for the production of light...

Cet article est le fruit d'une série de dix-sept entretiens avec Pierre Aigrain, menés de janvier 2001 à mai 2002, avec ses anciens collaborateurs, élèves et amis...

Silicon non linear optics is of considerable interest to the scientific community because of its applications to integrated optoelectronics. In order to observe non...

The fiber lasers are currently in the process of replacing their counterparts because of their high performance linked to a guided architecture, having direct impact...

Photocatalysis is recently extensively studied because it implies a variety of potential industrial applications ranging from the hydrogen generation of water...

Nitride semiconductors III N (AlN, GaN, InN) have interesting properties for micro-and opto-electronic applications. In use, they may be subjected to different types...

Semiconductor quantum dots attract a lot of attention for their application in many fields such as optoelectronic and biology. In the study, we investigated optical...

In the framework of light-atom interaction, laser diodes need specific optical performances: high power and narrow linewidth (around 852nm or 894nm for Cesium atoms,...

Growth of Au-catalysed ZnSe NWs has been successfully achieved on ZnSe peudo-substrates grown on GaAs substrate for the 1st time. Nucleation of the gold catalyst...
