Fabrication and characterization of lithium-diffused inverted coaxial point-contact HPGe detectors
Anupama Karki, Kunming Dong, Dongming Mei
High-purity germanium (HPGe) detectors with low capacitance, low electronic noise, and stable high-voltage operation are important for high-resolution gamma-ray spectroscopy and ra…

Post-diffusion cooling effects on Hall-derived active lithium donor profiles in high-purity germanium
Kunming Dong, Dongming Mei, Anupama Karki +2
Lithium (Li) diffusion is commonly used to form contacts in high-purity germanium (HPGe) detectors, but the final electrically active donor profile can be sensitive to the…

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)…
