    Abstract:

    HgCdTe APD is one of the developing trends of third generation inferred FPA detectors. In this paper we report the result on a 1616 arrays of HgCdTe avalanche photodiode with 3.56 μm cutoff wavelength. The operability in gain exceeds 90% and relative gain dispersion is lower than 20%. NEPh is about 60 at 6 V bias with excess noise factor close to 1.2.
