Gain-Layer Project
Niels G. Sorgenfrei, Anna Rita Altamura, Cristina Besleaga +18
Gain-layer degradation from exposure to radiation limits the use of Low-Gain Avalanche Diodes (LGADs) in high energy particle physics detector experiments. Proper understanding of…
On the nature and charge state of the X-Defect, a radiation-induced Silicon defect with field-enhanced charge carrier emission
Niels Sorgenfrei, Yana Gurimskaya, Anja Himmerlich +4
The elusive X-Defect, a defect found in low-resistivity -type Silicon after irradiation, observed as a low-temperature shoulder of the $\mathrm{B}_\mathrm{i}\mathrm{O}_\mathrm{i…
Characterisation of Crystalline Defects in 4H Silicon Carbide using DLTS and TSC
Niels Sorgenfrei, Elias Arnqvist, Yana Gurimskaya +4
Future hadron collider experiments will require sensing materials that withstand stronger radiation fields. Therefore, either a frequent replacement of detectors, a significant inc…
Defects and acceptor removal in 60Co γ-irradiated p-type silicon
Anja Himmerlich, Núria Castelló-Mor, Esteban Currás-Rivera +11
Boron-doped silicon detectors used in high radiation environments like the future HL-LHC show a degradation in device performance due to the radiation induced deactivation of the a…
