    • Exciton confinement in homo- and heteroepitaxial ZnO/Zn(1-x)Mg(x)O quantum wells with x < 0.1 

      Laumer, Bernhard; Wassner, Thomas A.; Schuster, Fabian; Stutzmann, Martin; Schörmann, Jörg; Rohnke, Marcus; Chernikov, Alexej; Bornwasser, Verena; Koch, Martin; Chatterjee, Sangam; Eickhoff, Martin (2011)
      ZnO/Zn(1 - x)Mg(x)O single quantum well (SQW) structures with well widths d(W) between 1.1nm and 10.4 nm were grown by plasma-assisted molecular beam epitaxy both heteroepitaxially on c-plane sapphire and homoepitaxially ...
    • Intra-excitonic relaxation dynamics in ZnO 

      Chernikov, Alexej; Koch, Martin; Laumer, Bernhard; Wassner, Thomas A.; Eickhoff, Martin; Koch, Stephan W.; Chatterjee, Sangam (2011)
      The temperature and carrier-density dependent excitonic relaxation in bulk ZnO is studied by means of time-resolved photoluminescence. A rate-equation model is used to analyze the population dynamics and the transitions ...
    • Optical properties of MgZnO alloys: Excitons and exciton-phonon complexes 

      Neumann, M. D.; Cobet, C.; Esser, N.; Laumer, Bernhard; Wassner, T. A.; Eickhoff, Martin; Feneberg, M.; Goldhahn, R. (2011)
      The characteristics of the excitonic absorption and emission around the fundamental bandgap of wurtzite Mg(x)Zn(1-x)O grown on c-plane sapphire substrates by plasma assisted molecular beam epitaxy with Mg contents between ...
