利用飞秒和皮秒四波混频测量了激子和双激子在不同激发强度和温度下的退相时间T2随频率的变化。在不同的散射机制的框架中讨论了它们的行为。由此，双激子声学和光学声子散射截面的确定。
The dephasing time T2 of excitons and biexcitons is measured by femtosecond and picosecond four-wave mixing as function of frequency for different excitation intensities and temperatures. Their behavior is discussed in the frame of different scattering mechanisms. From this, the biexciton acoustic- and optical-phonon scattering cross sections are determined.
