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…

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…

The impact of neutral impurity concentration on charge drift mobility in n-type germanium

H. Mei, G. -J. Wang, G. Yang +1

The impact of neutral impurity scattering of electrons on the charge drift mobility in high purity n-type germanium crystals at 77 Kelvin is investigated. We calculated the contrib…

Crystal growth and detector performance of large size high-purity Ge crystals

Guojian Wang, Mark Amman, Hao Mei +4

High-purity germanium crystals approximately 12 cm in diameter were grown in a hydrogen atmosphere using the Czochralski method. The dislocation density of the crystals was determi…
