Abstract
We report on a study of several different electrode technologies to avoid t he "dead-layer" problem in ionization and phonon-based dark matter detector s. We have found the most success with an amorphous blocking-layer electrod e structure, and have demonstrated background electron rejection of approxi mate to 95% above 20 keV.
