Observation of Nonequilibrium Carrier Distribution in Ge, Si and GaAs by Terahertz-pump--Terahertz-probe Measurements
Janos Hebling, Matthias C. Hoffmann, Harold Y. Hwang +2
We compare the observed strong saturation of the free carrier absorption in n-type semiconductors at 300 K in the terahertz frequency range when single-cycle pulses with intensitie…

THz-pump -- THz-probe spectroscopy of semiconductors at high field strengths
Matthias C. Hoffmann, Janos Hebling, Harold Y. Hwang +2
Pumping n-type GaAs and InSb with ultrafast THz pulses having intensities higher than 150 MW/cm2 shows strong free carrier absorption saturation at temperatures of 300 K and 200 K…
