Description
The carrier recombination properties of semiconductors are critically influenced by defect species introduced by irradiations. In particle detectors, a reduction in carrier lifetime correlates with the degradation of charge collection efficiency and with an increase of leakage current. To develop radiation hard particle sensors and to predict variations of sensor functional parameters with aging, the investigation of recombination processes in pristine and irradiated detector materials is of paramount importance.
In this talk, carrier recombination characteristics in Si, irradiated by reactor neutrons up to extreme fluences (1018 cm-2), will be considered. The results were obtained by the contactless microwave probed photoconductivity transients technique and the pump-probe setup by employing femtosecond laser pulses.
