Abstract
The demonstration of D-* in excess of 2 x 10(9)cmHz(1/2)W(-1) from 1 mm dia meter, uncooled, semiconductor diode detectors with a pak wavelength respon se at 5 mum is reported. They are based on heterostructures in the In1-xAlx Sb alloy system and employ hyperspherical optical immersion. The devices ha ve sufficiently high impedance for convenient amplifier matching, without s ignal-to-noise degradation, and the potential for high frequency response a bove 100 kHz.
