Abstract
The frequency dependence of two-photon absorption is measured over a wide range in InSb and Hg0.78Cd0.22Te, showing good agreement with a nonparabolic-band perturbation calculation and wide divergence from "tunneling" theory. Associated photoconductivity measurements, required in the analysis, confirm that Auger scattering is the dominant process at room temperature in n-InSb, but at low temperatures have yielded a direct value of the lifetime of (77 K)=143 ns for radiative recombination. © 1980 The American Physical Society.
