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>"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"230"},{"_id":"35"}],"user_id":"16199","_id":"54867","language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"article_type":"original","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"790"},{"_id":"642"},{"_id":"286"},{"_id":"429"},{"_id":"230"},{"_id":"27"},{"_id":"35"},{"_id":"169"}],"user_id":"16199","_id":"54868","project":[{"name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"name":"TRR 142 - A: TRR 142 - Project Area A","_id":"54"},{"_id":"55","name":"TRR 142 - B: TRR 142 - Project Area B"},{"_id":"166","name":"TRR 142 - A11: TRR 142 - Subproject A11"},{"name":"TRR 142 - B07: TRR 142 - Polaronen-Einfluss auf die optischen Eigenschaften von Lithiumniobat (B07*)","_id":"168"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"status":"public","abstract":[{"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.

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>","lang":"eng"}],"publication":"Small","type":"journal_article","doi":"10.1002/smll.202311635","title":"DFT‐Assisted Investigation of the Electric Field and Charge Density Distribution of Pristine and Defective 2D WSe<sub>2</sub> by Differential Phase Contrast Imaging","author":[{"full_name":"Groll, Maja","last_name":"Groll","first_name":"Maja"},{"first_name":"Julius","last_name":"Bürger","id":"46952","full_name":"Bürger, Julius"},{"first_name":"Ioannis","id":"87911","full_name":"Caltzidis, Ioannis","last_name":"Caltzidis"},{"last_name":"Jöns","full_name":"Jöns, Klaus D.","id":"85353","first_name":"Klaus D."},{"id":"468","full_name":"Schmidt, Wolf Gero","orcid":"0000-0002-2717-5076","last_name":"Schmidt","first_name":"Wolf Gero"},{"first_name":"Uwe","last_name":"Gerstmann","orcid":"0000-0002-4476-223X","full_name":"Gerstmann, Uwe","id":"171"},{"first_name":"Jörg K.

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.

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>","lang":"eng"}],"date_created":"2024-06-24T06:26:02Z","author":[{"last_name":"Franzke","full_name":"Franzke, Katharina","first_name":"Katharina"},{"orcid":"0000-0002-2717-5076","last_name":"Schmidt","full_name":"Schmidt, Wolf Gero","id":"468","first_name":"Wolf Gero"},{"orcid":"0000-0002-4476-223X","last_name":"Gerstmann","id":"171","full_name":"Gerstmann, Uwe","first_name":"Uwe"}],"volume":2701,"publisher":"IOP Publishing","date_updated":"2025-12-05T13:36:01Z","doi":"10.1088/1742-6596/2701/1/012094","title":"Relativistic calculation of the orbital hyperfine splitting in complex microscopic structures","issue":"1","publication_status":"published","publication_identifier":{"issn":["1742-6588","1742-6596"]},"citation":{"chicago":"Franzke, Katharina, Wolf Gero Schmidt, and Uwe Gerstmann. “Relativistic Calculation of the Orbital Hyperfine Splitting in Complex Microscopic Structures.” <i>Journal of Physics: Conference Series</i> 2701, no. 1 (2024). <a href=\"https://doi.org/10.1088/1742-6596/2701/1/012094\">https://doi.org/10.1088/1742-6596/2701/1/012094</a>.","ieee":"K.

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>","lang":"eng"}],"status":"public","type":"journal_article","publication":"APL Quantum","title":"Time-bin entanglement in the deterministic generation of linear photonic cluster states","doi":"10.1063/5.0214197","date_updated":"2025-12-05T13:55:00Z","publisher":"AIP Publishing","date_created":"2025-12-04T12:35:53Z","author":[{"last_name":"Bauch","full_name":"Bauch, David","first_name":"David"},{"first_name":"Nikolas","full_name":"Köcher, Nikolas","id":"79191","last_name":"Köcher"},{"id":"90283","full_name":"Heinisch, Nils","orcid":"0009-0006-0984-2097","last_name":"Heinisch","first_name":"Nils"},{"full_name":"Schumacher, Stefan","id":"27271","last_name":"Schumacher","orcid":"0000-0003-4042-4951","first_name":"Stefan"}],"volume":1,"year":"2024","citation":{"ama":"Bauch D, Köcher N, Heinisch N, Schumacher S.
