Propagation of coherent small-area picosecond laser pulses in resonance with the acceptor-bound (I1) exciton in CdS results in pronounced beating. The analysis in terms of the coupled Maxwell-optical Bloch equations demonstrates the evolution of a 0蟺-pulse and gives a dephasing time of 65 ps....
Mobility Limitations by Interface Scattering in Modulation-Doped CdS/ZnSe Single Quantum Wells73.21.Fg73.50.Bk73.63.HsS8.15We examined the electrical properties of modulation-doped CdS/ZnSe single quantum wells grown by molecular beam epitaxy. The n-doping was performed in the ZnSe barrier material ...
