We have studied the dynamic properties of a single spin (Mn impurity or resident electron) in a II-VI semiconductor quantum dot. A quantum dot doped with a single Mn...

We have studied the spin dynamics of an individual Mn atom embedded a CdTe quantum dot. Our results show that the Mn spin relaxation is faster when the quantum dot...

We have studied the growth and the properties of InAsP/InP(001) quantum dots made by metal-organic vapor phase epitaxy for the realization of 1.55 µm single photon...

In the framework of this thesis, single InAs/GaAs quantum dot devices were studied by optical means. Starting with a general description of self-assembled InAs QDs,...

My thesis focused on the study of photons and electrons con nement in several systems. First, I studied a new type of semiconductor nanocrystals to get at room...

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....

The spin of a carrier confined in a semiconductor quantum dot (QD) is an observable highly protected from the environment. It's a promising candidate to be a new...

The thesis focuses on quantum optical effects in semiconducting artificial atoms. We first investigate theoretically a single emitter coupled to a one-dimensional...

This thesis describes experiments on the synthesis of single wall carbon nanotubes (SWNTs), fabrication of ultra-clean CNT devices, and study of electronic properties...

This thesis work has focused on the synthesis of (In)GaN-based quantum dot (QD) structures by plasma-assisted molecular-beam epitaxy (PAMBE), deposited in both polar...

In this thesis we described a series of experimental works, which have been realized in the context of spin qubits, going from their use as information carriers to...

This thesis is devoted to the study of current correlation of single-electron beams in a ballistic quantum conductor. A mesoscopic capacitor is used as an on-demand...

This PhD thesis is at a cross-road between three different fields : the spintronics which uses the spin degree of freedom of the electron to build new devices ; the...

Semiconductor quantum dots offer an attractive route towards efficient and high-quality photon sources for optical quantum information applications, with potential for...
