Abstract

Using picosecond pulses from a free-electron laser, we have carried out a pump-probe determination of Shockley-Read-Hall (SRH) and Auger free-carrier recombination lifetimes in two long-wave (6-7 µm) W-structure laser with InAs/Ga₁__xIn_xSb/InAs/AlSb active regions. The SRH coefficient is nearly constant (A ? 4.0 × 10⁸ s^-1), while the Auger coefficient has an upper limit of C = 4.0 × 10^-27 to 2.2 × 10^-27 cm⁶/s in the temperature range 40-230 K. This represents an order of magnitude Auger suppression compared to type-I III-V semiconductors with the same energy gap.
