Description

The collection of charge carriers injected close to the Si Si02 interface of p on n silicon strip sensors was investigated using a red laser TCT setup. The sensors were investigated non-irradiated and after 1 MGy 12 keV photon irradiation. The relation between charge collection and accumulation layer was studied as well as the dependence on humidity and biasing history. A model of charge collection and charge carrier losses at the interface was developed. Results will be presented and discussed.
