Photon-assisted ultrafast electron-hole plasma expansion in direct band semiconductors
T. Troha, F. Klimovič, T. Ostatnický +2
Time-resolved terahertz spectroscopy is used to investigate formation and ultrafast long-distance propagation of electron-hole plasma in strongly photoexcited GaAs and InP. The obs…
