19 September 2016 Extended short wavelength infrared HgCdTe detectors on silicon substrates
Author Affiliations +
We report high-quality n-type extended short wavelength infrared (eSWIR) HgCdTe (cutoff wavelength ~2.59 μm at 77 K) layers grown on three-inch diameter CdTe/Si substrates by molecular beam epitaxy (MBE). This material is used to fabricate test diodes and arrays with a planar device architecture using arsenic implantation to achieve p-type doping. We use different variations of a test structure with a guarded design to compensate for the lateral leakage current of traditional test diodes. These test diodes with guarded arrays characterize the electrical performance of the active 640 × 512 format, 15 μm pitch detector array.
