The final results of the EDELWEISS-I dark matter search using cryogenic heat-and-ionization Ge detectors are presented. The final data sample corresponds to an increase by a factor five in exposure relative to the previously published results. A recoil energy threshold of 13 keV or better was achieved with three 320 g detectors working simultaneously over four months of stable operation. Limits on the spin-independent cross-section for the scattering of a WIMP on a nucleon are derived from an accumulated fiducial exposure of 62 kg·d.

“…These detectors are nearly identical to the detectors (Figs. J1, J2) developed by the Lawrence Berkeley National Laboratory (LBNL) for the Nuclear Compton Telescope (NCT) balloon payload [12], utilizing their pioneering amorphous Ge contact technologies [66]. These GeDs operate as fully-depleted p-i-n junctions, with the blocking electrode made from a ~0.1-µm thick layer of amorphous Ge which is deposited on the entire detector surface.…”

“…Even so, substantial progress has been made in the development of these detectors [1][2][3][4][5][6][7][8][9][10][11]. One advancement has been the amorphous semiconductor contact technology [10][11][12][13]. This technology offers the advantages of producing contacts that have thin dead layers, can be fine-pitched, and exhibit good blocking behavior under either bias polarity.…”
