Wavelength selective photoexcitation of picosecond acoustic-phonon pulses in a triple GaAs/Al0.3Ga0.7As quantum well structure
Ultrashort coherent phonon-pulse generation and detection is investigated in a GaAs-Al0.3Ga0.7As quantum well structure containing three wells of different widths using an optical pump and probe method. The pump photon energy is tuned to the region of the hh1-e1 transition energies of the wells and...
