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.

Flat-band ratio and quantum metric in the superconductivity of modified Lieb lattices

Communications Physics
Flat bands may offer a route to high critical temperatures of superconductivity. It has been predicted that the quantum geometry of the bands as well as the ratio of the number of flat bands to the number of orbitals determine flat band superconductivity.

Molecular Design Strategies for High‐Voltage Organic Cathodes

Advanced Energy Materials, EarlyView.
This work proposes molecular engineering strategies for high‐voltage organic cathode materials for Li‐ion batteries: (1) increase Li‐O coordination number (CN), (2) achieve a greater increase in aromaticity upon reduction (∆Aromaticity), and (3) add an electron‐withdrawing group (EWG), through a combined experimental and computational study on reported

design and development of a vibrating sample magnetometer for high magnetic field measurements of superconductors [PDF]

, 1994
A Vibrating Sample Magnetometer (VSM) has been designed, constructed and developed. The design specification was for a VSM to work in magnetic fields up to 15T, and provide a variable temperature environment for the sample from 4.2K to 130K.

Alternative designs of high-temperature superconducting synchronous generators

, 2010
This paper discusses the different possible designs of both cored and coreless superconducting synchronous generators using high-temperature superconducting (HTS) tapes, with particular reference to demonstrators built at the University of Southampton ...

Observation of superconductivity in a nontrivial $${{{{\mathcal{Z}}}}}_{2}$$ Z 2 approximant quasicrystal

Communications Materials
Superconductivity and nontrivial topology are highly sought-after phenomena in quantum materials. While many topological crystalline materials have been found to exhibit superconductivity, their presence in quasicrystals—materials with a unique aperiodic

Automatic Determination of Quasicrystalline Patterns from Microscopy Images

Advanced Intelligent Discovery, EarlyView.
This work introduces a user‐friendly machine learning tool to automatically extract and visualize quasicrystalline tiling patterns from atomically resolved microscopy images. It uses feature clustering, nearest‐neighbor analysis, and support vector machines. The method is broadly applicable to various quasicrystalline systems and is released as part of

High-temperature superconductivity from realistic Coulomb and Frohlich interactions [PDF]

, 2012
In recent years ample experimental evidence has shown that charge carriers in high-temperature superconductors are strongly correlated but also coupled with lattice vibrations (phonons), signalling that the true origin of high-Tc superconductivity can ...

Materials Representation Learning Based on a Material–Motif Network and Heterogeneous Graphs

Advanced Intelligent Discovery, EarlyView.
Structure motifs in materials are used to construct a bipartite material–motif network that links each material to its constituent motifs and establishes connectivity among materials sharing common motifs. Network analysis reveals material clusters associated with different functional applications and supports motif‐guided screening of materials.
