| Charge collection and electrode structures in ionization and phonon based dark matter detectors (2002) | |||||||||||||||
Abstract | |||||||||||||||
| We report on progress in our understanding of the physics of of implanted contacts, amorphous layer structures and Schottky contacts on detectors based on the simultaneous ionization and phonon based at 20 mK. Loss of charge for events near the contacts limits the capabilities of these detectors for detecting dark matter, an effect which is minimized by use of amorphous blocking layers. | |||||||||||||||
