Temperature-Dependent Charge Transport in USD-Grown High-Purity Germanium: Interplay Between Freeze-Out and Multi-Scattering Mechanisms
Narayan Budhathoki, Dongming Mei, Abhinna Rajbanshi +1
We report temperature-dependent charge transport measurements in p-type high-resistivity germanium crystals grown at the University of South Dakota. Hall-effect and four-probe resi…
AIMBio-Mat: An AI-Native FAIR Platform for Closed-Loop Materials Discovery and Biomedical Translation
D. -M. Mei, K. Acharya, C. M. Adhikari +51
Materials discovery and biomedical translation increasingly require models that can reason across composition, processing, structure, biological response, manufacturability, safety…
Machine-Learning Optimization of Detector-Grade Yield in High-Purity Germanium Crystal Growth
Athul Prem, Dongming Mei, Sanjay Bhattarai +2
High-purity germanium (HPGe) crystals underpin some of the most sensitive detectors used in fundamental physics and other high-resolution radiation-sensing applications. Despite th…
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…
