The leading candidate to generate such pairs is based on spontaneous parametric down-conversion (SPDC) in non-linear crystals. However, its pair extraction efficiency is limited to 0.1% when operating at near-unity fidelity due to multiphoton emission at high brightness. Quantum dots in photonic nanostructures can in principle overcome this limit, but the devices with high entanglement fidelity (99%) have low pair extraction efficiency (0.01%). Here, we show a measured peak entanglement fidelity of 97.5% ± 0.8% and pair extraction efficiency of 0.65% from an InAsP quantum dot in an InP photonic nanowire waveguide. We show that the generated oscillating two-photon Bell state can establish a secure key for peer-to-peer QKD. Using our time-resolved QKD scheme alleviates the need to remove the quantum dot energy splitting of the intermediate exciton states in the biexciton-exciton cascade.</jats:p>","lang":"eng"}]},{"status":"public","editor":[{"first_name":"Philip R.","last_name":"Hemmer","full_name":"Hemmer, Philip R."},{"full_name":"Migdall, Alan L.","last_name":"Migdall","first_name":"Alan L."}],"type":"conference","publication":"Quantum Computing, Communication, and Simulation IV","language":[{"iso":"eng"}],"user_id":"48188","department":[{"_id":"623"}],"_id":"62852","citation":{"ama":"Gyger S, Tao M, Colangelo M, et al.

In the field of polymeric gas separation membranes, a beneficial impact on stability and membrane performance is known for several polymers with differing functional groups. This study for the first time investigates VPI of trimethylaluminum (TMA) into poly(1‐trimethylsilyl‐1‐propyne) (PTMSP), featuring a carbon–carbon double bond as functional group. Saturation of the precursor inside the polymer is already attained after 60 s infiltration time leading to significant densification of the material. Depth profiling proves accumulation of aluminum in the polymer itself, but a significantly increased accumulation is visible in the gradient layer between polymer and SiO<jats:sub>2</jats:sub> substrate. A reaction pathway is proposed and supplemented by density‐functional theory (DFT) calculations. Infrared spectra derived from both experiments and simulation support the presented reaction pathway. In terms of permeance, a favorable impact on selectivity is observed for infiltration times up to 1 s. Longer infiltration times yield greatly reduced permeance values close or even below the detection limit of the measurement device. The present results of this study set a strong basis for the application of VPI on polymers for gas‐barrier and membrane applications in the future.</jats:p>"}],"user_id":"54556","department":[{"_id":"302"}],"_id":"62873","language":[{"iso":"eng"}],"article_number":"2400171","issue":"28","publication_status":"published","publication_identifier":{"issn":["2196-7350","2196-7350"]},"citation":{"ama":"Jenderny J, Boysen N, Rubner J, et al.

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).

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>","lang":"eng"}],"status":"public","_id":"54867","user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"230"},{"_id":"35"}],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2367-198X","2367-198X"]},"issue":"11","year":"2024","citation":{"ieee":"T.

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"}],"type":"journal_article","publication":"Small","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","date_created":"2024-06-24T09:46:25Z","author":[{"first_name":"Maja","full_name":"Groll, Maja","last_name":"Groll"},{"first_name":"Julius","last_name":"Bürger","full_name":"Bürger, Julius","id":"46952"},{"last_name":"Caltzidis","id":"87911","full_name":"Caltzidis, Ioannis","first_name":"Ioannis"},{"first_name":"Klaus D.","last_name":"Jöns","full_name":"Jöns, Klaus D.","id":"85353"},{"id":"468","full_name":"Schmidt, Wolf Gero","orcid":"0000-0002-2717-5076","last_name":"Schmidt","first_name":"Wolf Gero"},{"orcid":"0000-0002-4476-223X","last_name":"Gerstmann","full_name":"Gerstmann, Uwe","id":"171","first_name":"Uwe"},{"id":"20797","full_name":"Lindner, 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. 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.
