  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 (NTLE), 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 last results of a Neganov-Trofimov-Luke effect light detector
with an electric field configuration optimized to improve the charge collection
within the absorber.
