Area-dependent gain and noise characteristics of mid-wavelength infrared HgCdTe planar electron avalanche photodiodes

Area-dependent gain and noise characteristics of mid-wavelength infrared HgCdTe planar electron avalanche photodiodes

This paper mainly investigates the area-dependent gain and noise characteristics of mid-wavelength infrared (MWIR) Hg _0.7 Cd _0.3 Te planarelectron avalanche photodiodes (e-APDs) operated at 80 K. The 10- μ m-radius diode exhibits low dark current in the magnitude of 10 ^–13 A below −5.5 V, high ga...
