摘要：

The behavior of carrier-carrier screening is investigated in a GaAs-GaAlAs quantum-well structure by measuring the band-to-band polarization dephasing with femtosecond photon echoes. The variation of the electron-hole-polarization dephasing time with the carrier concentration reveals the two-dimensional character of the short-range screening between the interacting carriers.
