摘要：

The zero-phonon exciton line in GaAs has been investigated as a function of external electric field. The excitonic emission peak of the upper polariton branch shifted to higher photon energies when the external electric field was increased up to 20 V cm-1. Simultaneously, the electron temperature increased from 4.9K to 20K. Emission due to exciton-electron inelastic collision including lower polariton branch was also observed, showing the peak shift to lower photon energies. A model of the exciton motion and heating of the electron gas system has been proposed.
