Abstract

We measured the recombination lifetime of degenerate n-In_xGa_1-xAs for three different compositions that correspond to x = 0.53, 0.66, and 0.78 (band gaps of 0.74, 0.60, and 0.50 eV, respectively) over the doping range of 3 × 10¹⁸-5 × 10¹⁹ carriers/cm³. The Auger recombination rate increases slowly with decreasing band gap, and it matches the behavior predicted for phonon-assisted recombination.
