Effets d'un chauffage thermique sur les performances de miroirs multicouches Mo/Si, Mo/C et Ni/C pour le rayonnement X mou
No full textLes effets d'un chauffage thermique continu sur les performances en terme de réflectivité de miroirs multicouches Mo/Si, Mo/C, Ni/C sont étudiés. Les mesures de réflectivité autour de 100eV sont réalisées en utilisant le rayonnement synchrotron de Super-ACO au LURE. Des variations de réflectivité en fonction de la température sont enregistrées. On observe que la période du miroir Mo/Si décroßt, celui du miroir Mo/C reste constante et celle du miroir Ni/C croßt quand la température augmente. Ces comportements sont discutés dans le cadre de la science des matériaux.The effects of continuous thermal annealing on the performances in terms of reflectivity of Mo/Si, Mo/C, Ni/C multilayer mirrors are studied. The measurements of reflectivity around 100eV are performed by using the synchrotron radiation supplied by Super-ACO at the LURE. Variations of reflectivity versus the temperature are recorded. We observe that the period of the Mo/Si mirror decreases, the one of the Mo/C mirror remains constant and the one of the Ni/C increases as the annealing temperature increases. These behaviours are discuted in the framework of material science

Dopants
No full textThe applicability of XAFS to the structural study of dilute atoms is one of its main characteristics. It has been used extensively to study dopants in semiconductors, providing in many cases a structural basis for the understanding of physical properties. After a brief introduction to the use of XAFS in this field a review of the literature will be presented, ranging from the pioneering studies of As in amorphous Si to recent investigations on semiconductor systems of current interest
