Abstract

The picosecond decay of carriers in InGaAs, following photo excitation at photon energies just above the band edge, has been measured. A mode-locked neodymium:yttrium aluminum garnet pumped optical parametric amplifier provided the tunable, 35-ps pulses for excite-probe measurements. At carrier densities in excess of 10¹⁸ cm^-3 Auger processes are found to dominate the carrier recombination. We determine an Auger rate of 2.5±0.5×10^-28 cm⁶ s^-1.
