  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>The natural band
    alignments between indium phosphide and the main dioxides of titanium, i.e. rutile,
    anatase, and brookite as well as amorphous titania are calculated from the branch-point
    energies of the respective materials. Irrespective of the titania polymorph considered,
    type-I band alignment is predicted. This may change, however, in dependence on
    the microscopic interface structure: supercell calculations for amorphous titania
    grown on P-rich InP(001) surfaces result in a titania conduction band that nearly
    aligns with that of InP. Depending on the interface specifics, both type-I band
    and type-II band alignments are observed in the simulations. This agrees with
    recent experimental findings.</jats:p>"

  text: "<jats:p>\r\nArtificial leaves could be the breakthrough technology to overcome
    the limitations of storage and mobility through the synthesis of chemical fuels
    from sunlight, which will be an essential component of a sustainable future energy
    system. However, the realization of efficient solar‐driven artificial leaf structures
    requires integrated specialized materials such as semiconductor absorbers, catalysts,
    interfacial passivation, and contact layers. To date, no competitive system has
    emerged due to a lack of scientific understanding, knowledge‐based design rules,
    and scalable engineering strategies. Herein, competitive artificial leaf devices
    for water splitting, focusing on multiabsorber structures to achieve solar‐to‐hydrogen
    conversion efficiencies exceeding 15%, are discussed. A key challenge is integrating
    photovoltaic and electrochemical functionalities in a single device. Additionally,
    optimal electrocatalysts for intermittent operation at photocurrent densities
    of 10–20 mA cm<jats:sup>−2</jats:sup> must be immobilized on the absorbers with
    specifically designed interfacial passivation and contact layers, so‐called buried
    junctions. This minimizes voltage and current losses and prevents corrosive side
    reactions. Key challenges include understanding elementary steps, identifying
    suitable materials, and developing synthesis and processing techniques for all
    integrated components. This is crucial for efficient, robust, and scalable devices.
    Herein, corresponding research efforts to produce green hydrogen with unassisted
    solar‐driven (photo‐)electrochemical devices are discussed and reported.</jats:p>"

  text: <jats:title>Abstract</jats:title><jats:p>Most properties of solid materials
    are defined by their internal electric field and charge density distributions
    which so far are difficult to measure with high spatial resolution. Especially
    for 2D materials, the atomic electric fields influence the optoelectronic properties.
    In this study, the atomic‐scale electric field and charge density distribution
    of WSe<jats:sub>2</jats:sub> bi‐ and trilayers are revealed using an emerging
    microscopy technique, differential phase contrast (DPC) imaging in scanning transmission
    electron microscopy (STEM). For pristine material, a higher positive charge density
    located at the selenium atomic columns compared to the tungsten atomic columns
    is obtained and tentatively explained by a coherent scattering effect. Furthermore,
    the change in the electric field distribution induced by a missing selenium atomic
    column is investigated. A characteristic electric field distribution in the vicinity
    of the defect with locally reduced magnitudes compared to the pristine lattice
    is observed. This effect is accompanied by a considerable inward relaxation of
    the surrounding lattice, which according to first principles DFT calculation is
    fully compatible with a missing column of Se atoms. This shows that DPC imaging,
    as an electric field sensitive technique, provides additional and remarkable information
    to the otherwise only structural analysis obtained with conventional STEM imaging.</jats:p>

  text: <jats:title>Abstract</jats:title><jats:p>The current efficiency records for
    generating green hydrogen via solar water splitting are held by indium phosphide
    (InP)‐based photo‐absorbers, protected by TiO<jats:sub>2</jats:sub> layers grown
    through atomic layer deposition (ALD). InP is also a leading material for photonic
    integrated circuits and computing, where ultrafast near‐surface behavior is key.
    A previous study described electronic pathways at the phosphorus‐rich (P‐rich)
    surface of p‐doped InP(100) using time‐resolved two‐photon photoemission (tr‐2PPE)
    spectroscopy. Here, the intricate electron pathways of the P‐rich InP surface
    modified with ALD‐deposited TiO<jats:sub>2</jats:sub> are explored. Photoexcited
    bulk InP electrons migrate through a bulk‐to‐surface transition cluster of states
    and surface states and inject into the TiO<jats:sub>2</jats:sub> conduction band
    (CB). Energy levels and occupation dynamics of CB states in P‐rich InP and TiO<jats:sub>2</jats:sub>
    adlayers are observed, with discrete states preserved up to 10 nm TiO<jats:sub>2</jats:sub>
    deposition. Thermalization lifetimes of excited electrons &gt; 0.8 eV above the
    InP conduction band minimum (CBM) are preserved for layer thicknesses up to 2.5 nm.
    Annealing at 300 °C to achieve crystalline TiO<jats:sub>2</jats:sub> reconstructions
    destroys interfacial states, affecting charge transfer. These observations enable
    innovative engineering of the P‐rich InP/TiO<jats:sub>2</jats:sub> heterointerface,
    opening new possibilities for studying hot‐carrier extraction, adsorbate effects,
    surface plasmons, and improving photovoltaic and PEC water‐splitting devices.</jats:p>

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Theoretical spectroscopy
    based on double perturbation theory is typically challenged by systems with large
    orbital hyperfine splitting. Therefore, we here derive a rigorous, non-perturbative
    scheme starting from Dirac’s equation which allows to calculate the contribution
    of the orbital HFI for complex structures including heavy atoms with strong spin-orbit
    coupling (SOC). Using the PAW formalism, the method has been implemented in the
    software package Quantum ESPRESSO. We show that the ‘orbital part’ actually scales
    with SOC strength if orbital quenching is hindered by low local symmetry, i.e.
    in case of dimers or atoms at surfaces. This holds true in particular when the
    unpaired electron is localized in quasi-atomic <jats:italic>p</jats:italic>-like
    orbitals. Here, the orbital part is by far not negligible, but becomes dominant
    by surpassing the dipolar contribution by a factor of five.</jats:p>"

  text: <jats:p>Density-functional theory calculations on P-rich InP(001):H surfaces
    are presented. Depending on temperature, pressure and substrate doping, hydrogen
    desorption or adsorption will occur and influence the surface electronic properties.
    For p-doped samples, the charge transition levels of the P dangling bond defects
    resulting from H desorption will lead to Fermi level pinning in the lower half
    of the band gap. This explains recent experimental data. For n-doped substrates,
    H-deficient surfaces are the ground-state structure. This will lead to Fermi level
    pinning below the bulk conduction band minimum. Surface defects resulting from
    the adsorption of additional hydrogen can be expected as well, but affect the
    surface electronic properties less than H desorption.</jats:p>

  text: <jats:p>We theoretically investigate strategies for the deterministic creation
    of trains of time-bin entangled photons using an individual quantum emitter described
    by a Λ-type electronic system. We explicitly demonstrate the theoretical generation
    of linear cluster states with substantial numbers of entangled photonic qubits
    in full microscopic numerical simulations. The underlying scheme is based on the
    manipulation of ground state coherences through precise optical driving. One important
    finding is that the most easily accessible quality metrics, the achievable rotation
    fidelities, fall short in assessing the actual quantum correlations of the emitted
    photons in the face of losses. To address this, we explicitly calculate stabilizer
    generator expectation values as a superior gauge for the quantum properties of
    the generated many-photon state. With widespread applicability in other emitter
    and excitation–emission schemes also, our work lays the conceptual foundations
    for an in-depth practical analysis of time-bin entanglement based on full numerical
    simulations with predictive capabilities for realistic systems and setups, including
    losses and imperfections. The specific results shown in the present work illustrate
    that with controlled minimization of losses and realistic system parameters for
    quantum-dot type systems, useful linear cluster states of significant lengths
    can be generated in the calculations, discussing the possibility of scalability
    for quantum information processing endeavors.</jats:p>

    of ultra-thin polydimethylsiloxane (PDMS) layers resulted in a superhydrophobic
    surface. The modification steps were followed via Diffuse Reflectance Infrared

    A mechanism for the adsorption of PVAc at the two electrolyte/substrate interfaces

  text: The study validates an instrument for assessing digital competencies of teachers
    in vocational education, based on a TPACK extension which considers the knowledge
    sources of the dual subject matter. For validation, student teachers of vocational
    and business education in their first bachelor’s semester (n=112) were surveyed.
    In addition, student teachers in their first master’s semester (n=94) were surveyed
    to analyze the nomological validity of the instrument. The results confirm the
    assumed subdivision of content knowledge into the reference systems of profession
    and discipline. The model fit (χ2/df=1.284; RMSEA=0.051; CFI=0.948; SRMR=0.061)
    and the internal consistency of the scales can be rated as good. The nomological
    analysis of the instrument shows theoretically plausible results.

  text: <jats:sec><jats:title content-type="abstract-subheading">Purpose</jats:title><jats:p>Academic
    research has intensively analyzed the relationship between market concentration
    or market power and banking stability but provides ambiguous results, which are
    summarized under the concentration-stability/fragility view. We provide empirical
    evidence that the mixed results are due to the difficulty of identifying reliable
    variables to measure concentration and market power.</jats:p></jats:sec><jats:sec><jats:title
    content-type="abstract-subheading">Design/methodology/approach</jats:title><jats:p>Using
    data from 3,943 banks operating in the European Union (EU)-15 between 2013 and
    2020, we employ linear regression models on panel data. Banking market concentration
    is measured by the Herfindahl–Hirschman Index (HHI), and market power is estimated
    by the product-specific Lerner Indices for the loan and deposit market, respectively.</jats:p></jats:sec><jats:sec><jats:title
    content-type="abstract-subheading">Findings</jats:title><jats:p>Our analysis reveals
    a significantly stability-decreasing impact of market concentration (HHI) and
    a significantly stability-increasing effect of market power (Lerner Indices).
    In addition, we provide evidence for a weak (or even absent) empirical relationship
    between the (non)structural measures, challenging the validity of the structure-conduct-performance
    (SCP) paradigm. Our baseline findings remain robust, especially when controlling
    for a likely reverse causality.</jats:p></jats:sec><jats:sec><jats:title content-type="abstract-subheading">Originality/value</jats:title><jats:p>Our
    results suggest that the HHI may reflect other factors beyond market power that
    influence banking stability. Thus, banking supervisors and competition authorities
    should investigate market concentration and market power simultaneously while
    considering their joint impact on banking stability.</jats:p></jats:sec>
