Abstract

The first report of molecular beam epitaxial growth and performance of HgCdTe two-color detectors for the simultaneous detection of radiation at 4.1 and 4.5 mu m is presented. In-situ doped devices with the n-p-n architecture were grown by molecular beam epitaxy on (211)B CdZnTesubstrates. Representative structures exhibited x-ray rocking curves with full width at half-maxima of 40-60 arcs. The typical near surfaceetch pit density in these structures were 4-7 x 10(6) cm(-2). The devices were processed as mesa diodes and electrical contacts were made to the two n-type layers and the p-type layer to facilitate simultaneous operation of the two p-n junctions. The spectral response characteristics of the devices were characterized by sharp turn-on and turn-off for both bands, with R(0)A values > 5 x 10(5) Omega cm(2) at 77 K. Thedetectors exhibited quantum efficiencies > 70% in both bands.
