Paper Abstract

For the Cassini probe, focal plane number four of the Composite IR Spectrometer is equipped with a HgCdTe photovoltaic linear array. This 10 X 1 array detects in the 1100 to 1400 cm-1 wavenumber range with 200 X 200 micrometers 2 diodes at a pitch of 215 micrometers . Although background flux is near zero, peak detectivity, which is set by intrinsic diode noise, reaches 7.2 1011 cmHz.5W-1 at -30 mV bias whereas the theoretical limit is 7.8 1011 cmHz.5W-1. These performances are obtained by a simple ion implanted n/p planar technology on a liquid phase HgCdTe epilayer grown on lattice matched CdZnTe substrate.
