The quantum beats are observed as an oscillatory structure in the polarization decay of energetically closely spaced excitons which are coherently excited by ultrashort laser pulses.encoupled quantum wellsgekoppelte Quantum WellsIII-V HalbleiterIII-V semiconductorsphotoluminescencePLquantum wellstime resolved PLtunnelingtunnellingtunnelnZeitaufgelöste PL621667539journal article
