Substitutional impurity vs depth profiles generated by RBS. The anneals were 700 °C, 180 s for SPER, and 1300 °C, submillisecond for Witrynait to be one of the two largest impurity elements. Altogether 67 different impurity elements were found in the literature sources for the UO2 fuel. The largest impurity element in the zirconium alloys was either carbon or silicon. The number of impurity elements mentioned in the different literature sources were 24 (Zry-2), 74 (Zry-4) and …

WitrynaIn this thesis, the existence of impurity bound excitons is studied as a function of the impurity charge. This is done for a very simple one-dimensional toy-model, but using a rigorous mathematical approach. The results show that, for a sufficiently small impurity charge, such a system is stable and a bound state exists.
