title = "Dynamics of localized excitons and high-excitations effects in II-VI quantum wells and heterostructures",
abstract = "We investigate and discuss two aspects that are of importance for II-VI lasers, namely the dynamics of excitons and the high excitation processes capable to show optical gain. In the first case we concentrate on CdTe/ZnTe quantum wells, which exhibit an especially pronounced inhomogeneous broadening due to disorder. We investigate the relaxation of excitons under emission of optical and acoustic phonons. For the second topic we start with bulk II-VI compounds and proceed to thin layers, heterostructures and quantum wells, showing the excitonic effects are more important for II-VI laser materials as compared to the more established III-V compounds for the (infra)red, which are dominated by an electron-hole plasma.",

note = "Funding Information: Some of the experiments on the dynamics of excitons have been performed at the Max-Planck-Institut fiir Festk6rperforschung, Stuttgart. We thank Drs. S. Tartarenko and K. Saminadayar (Grenoble) for the cooperation in the growth of the CdTe/ZnTe samples at the Joint CEA-CNRS Group for Microstructures of II-VI Semiconductors. Valuable discussions with Prof. Dr. P. Thomas (Marburg), Prof. Dr. A. Nurmikko (Providence), Prof. Dr. Permogorov and Dr. Reznitsky (St. Petersburg) are gratefully acknowledged. Furthermore we should like to thank Prof. Dr. Nurmikko, Dr. Reznitsky, Prof. Dr. Permogorov and Prof. Dr. Suemune (Hiroshima) for making available to us some of their important results prior to publication. The work has been supported by the Deutsche For-schungsgemeinschaft and by the Materialschwer-punkt des Landes Rheinland-Pfalz at the University of Kaiserslautern.",
