    1. Front Cover: On the interpretation of wave function overlaps in quantum dots (Phys. Status Solidi B 4/2011)

      Søren Stobbe, Jørn M. Hvam and Peter Lodahl

      The overlap between electron and hole wave functions is a key parameter for quantum dots since it determines the oscillator strength and hence the spontaneous emission rate. A common and intuitive interpretation is that the electron and the hole must coincide spatially to recombine. Surprisingly, on pp. 855–858 of this issue, Stobbe, Hvam, and Lodahl show that this interpretation is not correct even loosely speaking. The cover illustration shows the electron (blue) and hole (red) wave functions for various quantum dot sizes (small, medium and large). This leads directly to the overlap integral (upper graph), which is remarkably different from the overlap probability (below) and implies that the oscillator strength is maximum when the overlap probability vanishes. These considerations lead to qualitative predictions, which agree with recent experiments and numerical calculations.

    1. Inside Back Cover: Spectral broadening and population relaxation in a GaAs interfacial quantum dot ensemble and quantum well nanostructure (Phys. Status Solidi B 4/2011)

      G. Moody, M. E. Siemens, A. D. Bristow, X. Dai, D. Karaiskaj, A. S. Bracker, D. Gammon and S. T. Cundiff

      Article first published online: 24 MAR 2011 | DOI: 10.1002/pssb.201190011

      The cover image shows a two-dimensional spectrum from a GaAs quantum well (QW) and interfacial quantum dot (QD) ensemble obtained using two-dimensional Fourier transform spectroscopy (2DFTS). This is a three-pulse four-wave mixing technique with the enhancement of interferometric stabilization of the excitation pulse delays, which allows a Fourier transform of the pulse delays to be taken. Using this technique, Galan Moody and co-workers (see pp. 829–832) are able to separate and isolate the spectral response of QW and QD excitons, measure the homogeneous linewidth in the presence of inhomogeneity, and measure relaxation and excitation exciton transfer rates between the QW and QD ensemble. Exciton–phonon coupling is investigated through temperature-dpendent measurements of the QD homogeneous linewidth and the QW–QD population transfer. The results indicate that elastic exciton–phonon coupling dominates the QD thermal broadening, while the QW→QD relaxation rate is over an order of magnitude larger than that for QD→QW excitation.

    1. Back Cover: Formation of epitaxial domains: Unified theory and survey of experimental results (Phys. Status Solidi B 4/2011)

      Marius Grundmann

      Article first published online: 24 MAR 2011 | DOI: 10.1002/pssb.201190012

      Epilayers Take Turns (M. Grundmann, pp. 805–824). You can park your car into a spot two ways: forward and backward. In the language of crystallography this corresponds to two rotation domains. How many equivalent ways can you fit a square on a hexagon? In crystal growth this problem arises for cubic ferroelectric barium titanate deposited on hexagonal zinc oxide, a prototype system for novel transparent, non-volatile memory cells. The answer is three. The inverse problem, hexagon on a square, yields a different number of only two possibilities. Considering the 10 two-dimensional point groups, all heteroepitaxial material combinations fall into one of 125 categories, depending on the symmetries and relative angular arrangement of substrate and epilayer. The number of epitaxial (rotation and mirror) domains has been derived now for all cases using group theory, helping in the design of novel heterostructures. Many examples from literature involving metals, semiconductors and dielectrics are categorized. Occasionally Nature allows additional domains – kind of allowing parallel parking as well.
