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…
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…
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…
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…
