There is a common need in Astroparticle experiments such as direct Dark Matter detection, neutrinoless double beta decay and coherent neutrino nucleus scattering experiments for detectors with a very low energy threshold. By employing the Neganov-Trofimov-Luke Effect (NTLE) the thermal signal of particle interactions in a semiconductor absorber, operated at cryogenic temperatures, can be amplified by drifting electrons and holes under an electric field inside the semiconductor. We present here the first results of a novel type of a NTLE light detector with a planar electric field configuration designed to improve the charge collection within the semiconductor. This research was supported by the DFG cluster of excellence “Origin and Structure of the Universe ”, by the Helmholtz Alliance for Astroparticle Physikcs, by the Maier-Leibnitz-Laboratorium (Garching) and by the BMBF.
