  text: '<jats:p>An ultra-fast change of the absorption onset for zincblende gallium-nitride
    (zb-GaN) (fundamental bandgap: 3.23 eV) is observed by investigating the imaginary
    part of the dielectric function using time-dependent femtosecond pump–probe spectroscopic
    ellipsometry between 2.9 and 3.7 eV. The 266 nm (4.66 eV) pump pulses induce a
    large electron–hole pair concentration up to 4×1020cm−3, which shift the transition
    energy between conduction and valence bands due to many-body effects up to ≈500 meV.
    Here, the absorption onset increases due to band filling while the bandgap renormalization
    at the same time decreases the bandgap. Additionally, the absorption of the pump-beam
    creates a free-carrier profile within the 605 nm zb-GaN layer with high free-carrier
    concentrations at the surface, and low concentrations at the interface to the
    substrate. This leads to varying optical properties from the sample surface (high
    transition energy) to substrate (low transition energy), which are taken into
    account by grading analysis for an accurate description of the experimental data.
    For this, a model describing the time- and position-dependent free-carrier concentration
    is formulated by considering the relaxation, recombination, and diffusion of those
    carriers. We provide a quantitative analysis of optical experimental data (ellipsometric
    angles Ψ and Δ) as well as a plot for the time-dependent change of the imaginary
    part of the dielectric function.</jats:p>'

  text: <jats:title>Abstract</jats:title><jats:p>Quantum well (QW) heterostructures
    have been extensively used for the realization of a wide range of optical and
    electronic devices. Exploiting their potential for further improvement and development
    requires a fundamental understanding of their electronic structure. So far, the
    most commonly used experimental techniques for this purpose have been all-optical
    spectroscopy methods that, however, are generally averaging in momentum space.
    Additional information can be gained by angle-resolved photoelectron spectroscopy
    (ARPES), which measures the electronic structure with momentum resolution. Here
    we report on the use of extremely low-energy ARPES (photon energy ~ 7 eV) to increase
    depth sensitivity and access buried QW states, located at 3 nm and 6 nm below
    the surface of cubic-GaN/AlN and GaAs/AlGaAs heterostructures, respectively. We
    find that the QW states in cubic-GaN/AlN can indeed be observed, but not their
    energy dispersion, because of the high surface roughness. The GaAs/AlGaAs QW states,
    on the other hand, are buried too deep to be detected by extremely low-energy
    ARPES. Since the sample surface is much flatter, the ARPES spectra of the GaAs/AlGaAs
    show distinct features in momentum space, which can be reconducted to the band
    structure of the topmost surface layer of the QW structure. Our results provide
    important information about the samples’ properties required to perform extremely
    low-energy ARPES experiments on electronic states buried in semiconductor heterostructures.</jats:p>

  text: We have investigated the stacking of self-assembled cubic GaN quantum dots
    (QDs) grown in Stranski–Krastanov (SK) growth mode. The number of stacked layers
    is varied to compare their optical properties. The growth is in situ controlled
    by reflection high energy electron diffraction to prove the SK QD growth. Atomic
    force and transmission electron microscopy show the existence of wetting layer
    and QDs with a diameter of about 10 nm and a height of about 2 nm. The QDs have
    a truncated pyramidal form and are vertically aligned in growth direction. Photoluminescence
    measurements show an increase of the intensity with increasing number of stacked
    QD layers. Furthermore, a systematic blue-shift of 120 meV is observed with increasing
    number of stacked QD layers. This blueshift derives from a decrease in the QD
    height, because the QD height has also been the main confining dimension in our
    QDs.
