Fabrication and Characterization of p-type Inverted Coaxial Point Contact (ICPC) Detectors with a-Ge Dual-Blocking Contacts
S. A. Panamaldeniya, K. M. Dong, D. M. Mei
We report the fabrication and characterization of two p-type inverted coaxial point contact (ICPC) high-purity germanium (HPGe) detectors, SAP16 and SAP17, produced from USD-grown…
Hybrid-Contact Planar HPGe Process Vehicle Toward Ring-Contact Designs
Kunming Dong, Dongming Mei, Shasika Panamaldeniya +3
Rare-event searches including dark matter, coherent elastic neutrino--nucleus scattering (CENS), and neutrinoless double-beta decay (0) require high-purity germanium (HPGe)…
Depletion-limited Effective Hall mobility in Micrometer-Scale High-Purity Germanium Crystals
Narayan Budhathoki, Dongming Mei, Sanjay Bhattarai +5
Electrostatic effects can strongly constrain charge transport in thinned high-purity germanium (HPGe), with direct implications for radiation detectors and Ge-based electronic and…
Virtual Majorana Neutrinos and the Minimum Neutrino Mass Scale in Neutrinoless Double-Beta Decay
Dongming Mei, Kunming Dong, Austin Warren +1
Virtual Majorana neutrinos are indispensable for neutrinoless double-beta (0) decay. In this study, we demonstrate that the overlap of the virtual Majorana neutrino wavefuncti…
