Impact of Charge Trapping on the Energy Resolution of Ge Detectors for Rare-Event Physics Searches
D. -M. Mei, R. B Mukund, W. -Z. Wei +14
Charge trapping degrades the energy resolution of germanium (Ge) detectors, which require to have increased experimental sensitivity in searching for dark matter and neutrinoless d…
Development of Planar P-type Point Contact Germanium Detectors for Low-Mass Dark Matter Searches
W. -Z. Wei, H. Mei, K. Kooi +5
The detection of low-energy deposition in the range of sub-eV through ionization using germanium (Ge) with a bandgap of 0.7 eV requires internal amplification of charge signa…
Implication of the Temperature-Dependent Charge Barrier Height of Amorphous Germanium Contact Detector in Searching for Rare Event Physics
R. Panth, W. -Z. Wei, D. -M. Mei +7
The exploration of germanium (Ge) detectors with amorphous Ge (a-Ge) contacts has drawn attention to the searches for rare-event physics such as dark matter and neutrinoless double…
Evidence of cluster dipole states in germanium detectors operating at temperatures below 10 K
D. -M. Mei, R. Panth, K. Kooi +5
By studying charge trapping in germanium (Ge) detectors operating at temperatures below 10 K, we demonstrate for the first time that the formation of cluster dipole states from res…
LEGEND-1000 Preconceptual Design Report
LEGEND Collaboration, N. Abgrall, I. Abt +261
We propose the construction of LEGEND-1000, the ton-scale Large Enriched Germanium Experiment for Neutrinoless Decay. This international experiment is designed to answer one…
The Impact of the Charge Barrier Height on Germanium (Ge) Detectors with Amorphous-Ge Contacts for Light Dark Matter Searches
W. -Z. Wei, R. Panth, J. Liu +3
Germanium (Ge) detectors with ability of measuring a single electron-hole (e-h) pair are needed in searching for light dark matter (LDM) down to the MeV scale. We investigate the f…
