Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

Advanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

Record Dissymmetry in Vibrational Optical Activity: Combining Vibronic Coupling and Aggregation in Cobalt(II) Camphorate Complexes

Angewandte Chemie, EarlyView.
The cobalt(II) bis(trifluoroacetylcamphorate) scaffold exhibits versatile coordination chemistry with solvent‐driven ligand exchange and geometrical rearrangements, associated with unique chiroptical properties. Microcrystalline suspension of [Co(tfc)2(CH3CN)2] revealed the largest VCD dissymmetry factor ever reported (g ≈ 0.2 at 1600 cm−1), arising ...

Horizons that gyre and gimble: a differential characterization of null hypersurfaces

European Physical Journal C: Particles and Fields
Motivated by the thermodynamics of black hole solutions conformal to stationary solutions, we study the geometric invariant theory of null hypersurfaces.

High‐Performance Solar‐Blind Photodetectors Enabled by Post‐Annealing Optimization of Solution‐Processed Ga2O3 Films

Advanced Electronic Materials, EarlyView.
Post‐annealing atmosphere and temperature are optimized to regulate oxygen‐related defect states in solution‐processed Ga2O3 films. The optimized H2/N2 annealing enables enhanced photoconductive gain while maintaining low dark current, leading to high‐performance solar‐blind photodetectors with a responsivity of 7.5 × 102 A W−1 under 254 nm ...

From Berzelius to Hyperspace: Previously Unrecognized Network of Reactivity in Textbook Brominations

Angewandte Chemie, EarlyView.
Robotic scans across multidimensional condition spaces of classic bromination reactions uncover regions of previously unrecognized reactivity, yielding new major products and novel substitution patterns. Correlation and anticorrelation analyses of product distributions across these hyperspaces enable reconstruction of the underlying mechanistic ...

Engineering a Correlated Narrow‐Gap Semiconductor: Effects of Ga Substitution in EuZn2P2

Advanced Electronic Materials, EarlyView.
ABSTRACT The effect of Ga substitution on the electronic, magnetic, and low‐energy responses of the Zintl phase EuZn2P2${\rm EuZn}_2 {\rm P}_2$ is investigated by electrical transport, electron spin resonance (ESR), and terahertz time‐domain spectroscopy (THz‐TDS). Incorporating Ga into EuZn2P2${\rm EuZn}_2 {\rm P}_2$ (EuZn1.8Ga0.2P2${\rm EuZn}_{1.8} {\

Determining the Relationship Between Composition, Structure, and Device Properties of GexSe1‐x‐Based Selector‐Only Memory

Advanced Electronic Materials, EarlyView.
Composition‐dependent structural evolution in GeXSe1‐X selector‐only memory (SOM) is correlated with device switching behavior. Increasing Ge strengthens network rigidity, suppresses atomic motion, and stabilizes threshold switching, while narrowing the memory window. The revealed structure–property relationship provides a guideline for compositionally

Selective Tuning of Perpendicular Magnetic Anisotropy and Dzyaloshinskii–Moriya Interaction in Heterostructures Compatible with Magnetic Tunnel Junctions

Advanced Electronic Materials, EarlyView.
ABSTRACT Chirally coupled magnetic tunnel junctions (MTJs) have been proposed as a route toward compact spin logic architectures. Micromagnetic simulations indeed show that chiral coupling between adjacent MTJs with perpendicular magnetic anisotropy (PMA) can be achieved through an in‐plane (IP) interconnection mediated by the Dzyaloshinskii–Moriya ...

Atomic‐Scale Tracing of Lithium Trapped in Copper Current Collectors

Advanced Energy Materials, EarlyView.
Does lithium diffuse into the copper current collector during cycling in lithium‐metal batteries? This study unveils, at the atomic scale, that lithium is trapped at grain boundaries and junctions, already after only one plating/stripping cycle. After three and more cycles, the copper foil surface becomes nanocrystalline and oxidized.
