Event-by-Event Space-Charge Gain Suppression in LGADs and Its Impact on Time Resolution

Djunes Janssens, Michael Moll, Heinrich Schindler

Low Gain Avalanche Detectors (LGADs) achieve time resolutions below 50 ps through internal charge multiplication, yet the gain is not a fixed device property as the space-charge 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…
