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…

Impact ionization in InSb probed by THz-pump THz-probe spectroscopy
Matthias C. Hoffmann, Janos Hebling, Harold Y. Hwang +2
Picosecond carrier dynamics in indium antimonide (InSb) following excitation by below-bandgap broadband far infrared radiation were investigated at 200 K and 80 K. Using a novel TH…
