Femtosecond studies in hot carrier relaxation in GaAs and AlGaAs

OSTI ID:7004215
Femtosecond carrier dynamics in GaAs and AlGaAs thin films were studied by femtosecond pump-probe absorption saturation spectroscopy. Identical pulse measurements monitor the rapid scattering of the carriers out of their initial, optically excited states. Multi-wavelength continuum probe investigations confirm the presence of the initial nonthermal carrier distribution as well as the appearance of state-filling throughout the band on a timescale of tens of femtoseconds. This presentation is represented by viewgraphs.
