Abstract
enUsing a generalized theory of the photoelectromagnetic (PEM) effect, the parameters of non-cooled InAs0.35Sb0.65 PEM far-infrared detectors are analysed. The responsivity Rv and detectivity D* are estimated in dependence of detector geometry and of recombination velocities at the surface. The highest values for Rv ≈ 0.1 V/W and for D* ≈ 105 m Hz1/2 W−1 at λ = 10.6 μm are obtained for p-type material with p/ni ≈ 10.
