Schottky Barrier Engineering in n‐Type Organic Source‐Gated Transistors Enabling High Conductance

Advanced Materials Technologies, EarlyView.
This study introduces a modified source electrode architecture for n‐type organic source‐gated transistors (OSGTs). By integrating Schottky and Ohmic contact regions, the design achieves a thinner depletion envelope, enhancing mobility nearly tenfold and reducing threshold voltage.

Large Anomalous Hall Effect, Non‐Vanishing Berry Curvature in (110) FeRh Antiferromagnet Films via Interface Strain

Advanced Science, EarlyView.
This study demonstrates a strain‐tunable anomalous Hall response in the (110)‐oriented FeRh thin film. First‐principles calculations reveal that strain‐induced symmetry lowering redistributes Berry curvature near the Fermi level via band shifts and avoided crossings.

Inter-Mesh Routing Algorithms in LEO Satellite Constellations Networks

Computing
Abstract In the quest for the sixth-generation (6G) mobile communication system, global coverage is paramount. Low-Earth orbit (LEO) satellite constellations (SatCon) play a pivotal role. The Walker-Delta SatCon architecture, with satellites in opposing meshes, shows promise.

Deformation Driven Suction Cups: A Mechanics‐Based Approach to Wearable Electronics

Advanced Science, EarlyView.
Deformation‐driven suction cups enable robust, reversible adhesion of wearable electronics to human skin spanning wide mechanical compliance, without adhesives or tight straps. By integrating mechanics modeling, experiments, and contact mechanics theory, this work reveals how cup geometry, substrate compliance, and interfacial adhesion govern suction ...
