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…
