Abstract

This paper is focused on forthcoming or planned experimental projects and R&D activities aiming to search for 0ν double beta decay (OνDBD) of 76Ge 106Cd and 64Zn by means of semiconductor detectors. Semiconductors detectors offer both exceptional intrinsic energy resolution, and extremely high intrinsic radiopurity. These features allow, once the external background is minimized, to reach high sensitivities on the half-life (T0ν1/2) of the OνDBD process i.e. on the effective Majorana neutrino mass |mee|. After a review of the pioneering and past experiments, the main experimental features, the attainable sensitivities on T0ν1/2 and |mee|, and the foreseen experimental schedule of GERDA, MAJORANA and COBRA will be reviewed.
