Abstract
Proton bombardment has been used to make n‐p junction ir detectors from epitaxial PbTe films on BaF2 substrates. When cooled at 77°K, these detectors are background limited at f/0.8; further reduction of the field of view gives Johnson‐noise‐limited peak detectivities of 6×1011 cm Hz1/2W−1 at f/20. The peak quantum efficiencies are 0.40–0.47.Keywords
