Spin‐Polarized Antiferromagnets for Spintronics

open access: yesAdvanced Materials, EarlyView.
This review highlights recent advances in anomalous and spin transport phenomena in spin‐polarized antiferromagnets. Key effects—including the anomalous Hall, Nernst, and magneto‐optical effects—are discussed across various antiferromagnetic platforms.

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

open access: yesAdvanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Machine Learning-Powered Course Allocation

open access: yesProceedings of the 25th ACM Conference on Economics and Computation
We study the course allocation problem, where universities assign course schedules to students. The current state-of-the-art mechanism, Course Match, has one major shortcoming: students make significant mistakes when reporting their preferences, which negatively affects welfare and fairness.

Localized Spin Textures Stabilized by Geometry‐Induced Strain in 2D Magnet Fe3GeTe2

open access: yesAdvanced Materials, EarlyView.
Strain engineering in 2D van der Waals ferromagnet Fe₃GeTe₂ is studied using scanning transmission X‐ray microscopy. Spatially varying strain from micropillar arrays induced local 10 K Curie temperature increases, stabilizing magnetic domains including skyrmions and skyrmion bags near pillar corners.

Mie‐Resonant Metasurfaces with Controlled Silicon Oxidation in Electron‐Beam Deposition

open access: yesAdvanced Materials Interfaces, EarlyView.
Electron‐beam deposition is optimized to prevent silicon oxidation by controlling chamber pressure and deposition rate, yielding refractive index values comparable to other methods. This tunability enables precise control of optical properties. Mie‐resonant metasurfaces exhibit strong, tunable collective resonances, allowing the fabrication of silicon ...

Joint subchannel power allocation for downlink NOMA systems based on quantum carnivorous plant algorithm

open access: yesJournal of King Saud University: Computer and Information Sciences
Currently, most existing research on non-orthogonal multiple access (NOMA) systems converts power allocation into two independent procedures, i.e., inter-subchannel power allocation and intra-subchannel power allocation.

Using Heat‐Cool Processing to Change the Assembly and Photoconductive Properties of Perylene Bisimides

open access: yesAdvanced Materials Interfaces, EarlyView.
Here, we demonstrate how heating and cooling cycles modulate the self‐assembly of amino acid‐appended perylene bisimides (PBIs), influencing their structural and optoelectronic properties. With the use of small angle neutron scattering, AFM, UV–vis absorption spectroscopy and rheology it is determined how this affects their performance in perovskite ...
