Les laboratoires sur puce visent à miniaturiser et à intégrer les fonctions couramment utilisées dans les laboratoires d'analyse afin de cibler des applications en santé avec un impact prometteur sur le diagnostic médical au lit du patient. Les membranes poreuses sont d'un grand intérêt pour la préparation et l'analyse d'échantillon sur puce car elles permettent la séparation par taille/charge de molécules, mais également leur pré-concentration. Parmi les matériaux disponibles pour constituer des membranes poreuses, le silicium poreux présente de nombreux avantages tels que le contrôle précis

Abstract:

This thesis describes the development of silicon planar micro-calorimetric gas sensors employing a nanostructured palladium (Pd) catalyst. Present commercial, bead-type calorimetric sensors have been manufactured for nearly forty years and are used in many applications, such as mining, water treatment and emergency services, with an estimated European market value of €221M by 2004. However, recent advances in both silicon micro-machining and nano materials have created the technologies necessary to transform the present labour-intensive fabrication process in to a new low-cost batch production

Abstract:

The upgrade of the Large Hadron Collider (LHC) to the High Luminosity LHC (HL-LHC) will increase the requirements on radiation hardness of silicon sensors of the two multi-purpose experiments, ATLAS and CMS, at CERN. For this purpose the CERN RD50 collaboration is investigating radiation hard semiconductor detectors for high luminosity applications. The work for this thesis was done within this framework. Charge multiplication can be beneficial in this context because the collected charge of irradiated devices decreases with increasing irradiation fluence. Thus the effect of different read-out

Abstract:

To extend the physics reach of the LHC, upgrades to the accelerator are planned which will increase the integrated annual luminosity by a factor of 10 (to 250 - 300 fb$^{-1}$/ year). This will increase the occupancy and the radiation damage of the inner trackers. To cope with the elevated occupancy, the ATLAS experiment plans to introduce an all silicon inner tracker for use during High Luminosity LHC (HL-LHC) operation. With silicon, the occupancy can be adjusted by using the appropriate pitch for the pixels/micro-strips. Constraints due to high radiation damage mean that only sensors with el

In spite of the stablility (lack of reactivity) of diamond powder, I have developed a method for tethering alkyl chains and polymers to deuterium/hydrogen-terminated diamond.

The other method is atom transfer radical polymerization (ATRP), which was applied to grow polystyrene at the surface of diamond. Both polystyrene-modified diamond and sulfonated polystyrene-modified diamond can be prepared by either method, and can be

Abstract:

A theoretical and experimental investigation of scatter from surface roughness and core refractive index fluctuations in planar waveguides was performed, with an emphasis placed on applications in solution-deposited SiO₂-TiO₂ (silica titania) planar waveguiding systems. A perturbation theory was used to model TE₀ mode scattering from surface and volume microstructure, and to predict attenuation when provided with the necessary waveguide and scattering parameters. Final forms for the equations predicting surface and volume scatter losses into the cover and substrate regions of the waveguides we

Abstract:

Le Large Hadron Collider (LHC), située au CERN, Genève, produit des collisions de protons accélérés à une énergie de 3.5 TeV depuis le 23 Novembre 2009. L'expérience ATLAS enregistre depuis des données et poursuit sa recherche de nouvelle physique à travers l'analyse de la cinématique des événements issues des collisions. L'augmentation prévue de la luminosité sur la période s'étalant de 2011 2020 apportera de nouveaux défis pour le détecteur qui doivent être considérés pour maintenir les bonnes performance de la configuration actuelle. Le détecteur interne sera le sous-détecteur le plus affec

Abstract:

L'utilisation du sipos, pour la passivation des dispositifs planar haute tension est une technique de garde recente et prometteuse. Les caracteristiques du sipos sont rappelees et son principe d'utilisation, en tant que technique de garde, est decrit. La tenue en tension de composants silicium planar en technologie sipos est etudiee et les regles de conception, pour obtenir des tensions de claquage de 1000 v et 1500 v, sont etablies en fonction des parametres physiques et geometriques. Cette etude est menee a l'aide de simulations numeriques bidimensionnelles. Des dispositifs test sont realise

Abstract:

A fotônica em silício é um campo de pesquisas emergente com grande potencial para contribuir com a resolução de alguns dos problemas tecnológicos da atualidade. O gargalo imposto por interconexões metálicas na expansão da taxa de transmissão de dados em sistemas de comunicação como os de computadores de alto desempenho talvez seja um dos maiores desafios a serem superados. A propagação de luz em baixas velocidades de grupo e com controle de dispersão é uma das linhas de pesquisa atuais nas quais se busca explorar de forma mais eficiente as propriedades ópticas do silício, e assim, aumentar a c
