In this article, a non-inverting n+-on-p sensor was used at the Super LHC experiment to measure the leakage current increase, noise figures, electrical strip isolation, full depletion voltage evolution, and charge collection efficiency.
Abstract
Radiation tolerance up to 1015 1-MeV neq/cm2 is required for the silicon microstrip sensors to be operated at the Super LHC experiment. As a candidate for such sensors, we are investigating non-inverting n+-on-p sensors. We manufactured sample sensors of 1 times 1 cm in 4" and 6" processes with implementing different interstrip electrical isolation structures. Industrial high resistive p-type wafers from FZ and MCZ growth are tested. They are different in crystal orientations lang100rang and lang111rang with different wafer resistivities. The sensors were irradiated with 70-MeV protons and characterized in views of the leakage current increase, noise figures, electrical strip isolation, full depletion voltage evolution, and charge collection efficiency.

Accelerated annealing of n + -p strip detectors irradiated with pions

TL;DR: In this article, the authors presented charge collection measurements with silicon detectors with implanted n-type readout strips in p-type silicon bulk (n+p) and observed that irradiation of these detectors with pions results in only ~ 30% of the increase of VFD seen after irradiation with neutrons to the same NIEL equivalent fluence.
