Abstract
Cryogenic rare event searches based on heat and light composite calorimeters have a common need for large area photon detectors with high quantum efficiency, good radiopurity and high sensitivity. By employing the Neganov–Trofimov–Luke effect, the phonon signal of particle interactions in a semiconductor absorber operated at cryogenic temperatures can be amplified by drifting the photogenerated electrons and holes in an electric field. We present here the most recent results of a Neganov–Trofimov–Luke effect light detector with an electric field configuration optimized to improve the charge collection within the absorber.
