Abstract
Mercury cadmium telluride is a promising detector material for low background astronomical imaging and spectroscopy in the near infrared. We have begun a program to measure dark current as a function of temperature in both isolated HgCdTe diode arrays and arrays which have been bump-bonded to silicon multiplexers. In this paper, we describe measurements of 2.5 μm cutoff diode material and a hybrid array with a CCD readout. Measurements of 52 μm x 52 μm detectors indicate that id may be less than 50-100 e-/sec at 87 K.
