Abstract:
In this thesis, calculations of Auger recombination rates in semiconductor quantum wells are presented. Chapter One introduces Auger recombination, and the reasons for studying the Auger process are explained. Basically, Auger recombination is a non- radiative recombination mechanism that becomes more important as the carrier density increases and the bandgap decreases. In direct gap semiconductors, the Auger process has an activation energy, and the resulting highly temperature dependent Auger process is thought to be a possible cause of the high temperature sensitivity of long wavelength sem

Abstract:
Une radiothérapie efficace nécessite un dépôt de dose localisé à la tumeur, et donc un contraste entre le tissu tumoral et les tissus sains environnants. Une irradiation de basse énergie monochromatique au synchrotron d'une tumeur chargée en éléments lourds permet de maximiser l'interaction photoélectrique dans la tumeur et d'épargner les tissus sains, car les photoélectrons et les électrons Auger produits ont un TEL très élevé et déposent leur énergie autour des éléments lourds, augmentant fortement le dépôt de dose. Ils peuvent induire des dommages à l'ADN (cassures double brin) fortement lé

O mistério torna-se ainda maior devido à supressão (corte

Abstract:
L'observatoire Pierre Auger est une expérience de détection du rayonnement cosmique aux plus hautes énergies jamais mesurées. Ce dernier possède deux sous-ensembles de détection différents et complémentaires qui lui confèrent des capacités sans précédents pour l'étude du rayonnement cosmique. Le détecteur est également sensible aux neutrinos de ultra haute énergie, et ce bien qu'il n'ait pas été conçu dans ce but. Au cours de cette thèse, un programme de simulation a été développé afin d'étudier la propagation et l'interaction des neutrinos taus dans la croûte terrestre, travail nécessaire à l
