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…
Investigation of high resistivity p-type FZ silicon diodes after 60Co γ-irradiation
Chuan Liao, Eckhart Fretwurst, Erika Garutti +6
In this work, the effects of Co -ray irradiation on high resistivity -type diodes have been investigated. The diodes were exposed to dose values of 0.1, 0.2, 1, a…
Investigation of the Boron removal effect induced by 5.5 MeV electrons on highly doped EPI- and Cz-silicon
Chuan Liao, Eckhart Fretwurst, Erika Garutti +8
This study focuses on the properties of the BO (interstitial Boron~-~interstitial Oxygen) and CO (interstitial Carbon~-~interstitial Oxy…
Defect characterization studies on neutron irradiated boron-doped silicon pad diodes and Low Gain Avalanche Detectors
Anja Himmerlich, Nuria Castello-Mor, Esteban Curras Rivera +7
High-energy physics detectors, like Low Gain Avalanche Detectors (LGADs) that will be used as fast timing detectors in the High Luminosity LHC experiments, have to exhibit a signif…
Deep Diffused Avalanche Photodiodes for Charged Particles Timing
M. Centis Vignali, P. Dias De Almeida, L. Franconi +12
The upgrades of ATLAS and CMS for the High Luminosity LHC (HL-LHC) highlighted physics objects timing as a tool to resolve primary interactions within a bunch crossing. Since the e…
