| Research Abstract |
We aimed to transfer the excitons and to control their life time in semiconductor samples using the surface acoustic waves generated by the ultrashort light pulse absorption. For this purpose, we developed an experimental technique which allows the time resolved two-dimensional imaging of the GHz surface acoustic wave propagation and the two-dimensional imaging of the photoluminescence at the same region of the sample at low temperature (10K). Connecting to this, we also developed a heterodyne technique which use the modulated light for both excitation and probing light. We also developed an analyzing method for the strain components using the polarization of the probing light.
