Exploring Charge Transport Dynamics in a Cryogenic P-Type Germanium Detector
P. Acharya, M. Fritts, D. -M. Mei +3
This study explores the dynamics of charge transport within a cryogenic P-type Ge particle detector, fabricated from a crystal cultivated at the University of South Dakota (USD). B…
Observation of Time-Dependent Internal Charge Amplification in a Planar Germanium Detector at Cryogenic Temperature
P. Acharya, M. Fritts, D. -M. Mei +4
For the first time, time-dependent internal charge amplification through impact ionization has been observed in a planar germanium (Ge) detector operated at cryogenic temperature.…
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…
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…
Investigation of the Electrical Conduction Mechanisms in P-type Amorphous Germanium (a-Ge) Used as a-Ge Contacts for Ge Detectors
S. Bhattarai, R. Panth, W. -Z. Wei +5
Electrical conduction mechanisms in the disordered material system is experimentally studied for p-type amorphous germanium (a-Ge) used for high-purity Ge detector contacts. The lo…
Characterization of High-Purity Germanium (Ge) Crystals for Developing Novel Ge Detectors
M. -S. Raut, H. Mei, D. -M. Mei +5
High-purity germanium (HPGe) crystals are required to be well-characterized before being fabricated into Ge detectors. The characterization of HPGe crystals is often performed with…
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…
