Development of low-threshold detectors for low-mass dark matter searches with a p-type germanium detector operated at cryogenic temperature
Mathbar Raut, Dongming Mei, Sanjay Bhattarai +4
This study investigates new technology for enhancing the sensitivity of low-mass dark matter detection by analyzing charge transport in a p-type germanium detector at 5.2 K. To ach…
Development of Low-Threshold Detectors for Low-Mass Dark Matter Searches Using an N-Type Germanium Detector at 5.2 K
Sanjay Bhattarai, Dongming Mei, Rajendra Panth +4
We investigated charge transport in an n-type germanium detector at 5.2 K to explore new technology for enhancing low-mass dark matter detection sensitivity. Calculations of dipole…
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…
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…
Characterization of High-Purity Germanium Detectors with Amorphous Germanium Contacts in Cryogenic Liquids
R. Panth, J. Liu, I. Abt +6
For the first time, planar high-purity germanium detectors with thin amorphous germanium contacts were successfully operated directly in liquid nitrogen and liquid argon in a cryos…
