Lattice‐Distortion‐Driven Reduced Lattice Thermal Conductivity in High‐Entropy Ceramics

open access: yesAdvanced Science, EarlyView.
Long‐believed potential mechanisms of lattice distortion and mass fluctuation for the reduced lattice thermal conductivity are explored by designing two groups of high‐entropy diborides based on machine‐learning‐potential‐based molecular dynamics simulations.

No U(1) ‘electric-magnetic’ duality in Einstein gravity

open access: yesJournal of High Energy Physics
We revisit the question of whether classical general relativity obeys, beyond the linearised order, an analogue of the global U(1) electric-magnetic duality of Maxwell theory, with the Riemann tensor playing the role analogous to the field strength ...

High‐Throughput Production of Electrically Conductive Yarn (E‐Yarn) for Smart Textiles

open access: yesAdvanced Electronic Materials, EarlyView.
This study introduces a versatile, scalable manufacturing method to produce Nylon yarn coated with a thin layer of an electrically conductive, silver‐filled, polyamide‐based compound, achieving a resistivity of 7.5 Ω cm−1. The yarn withstands bending and washing, enabling smart textile applications.

Vertical Phase Separation in Blended Organic Semiconducting Films and Impact on Their Electrical and Direct X‐Ray Detection Properties

open access: yesAdvanced Electronic Materials, EarlyView.
The composition of blends of 1,4,8,11‐tetramethyl‐6,13‐triethylsilylethynyl pentacene (TMTES) and polystyrene (PS) to be used in Organic Field‐Effect Transistors (OFETs) is optimized to achieve and enhance thin film crystallinity and a reduced charge trap density at the semiconductor/dielectric interface.

Configuration and Charge Dynamics of Defect‐Cluster‐Dipoles in CaTiO3 for Enhanced Permittivity

open access: yesAdvanced Electronic Materials, EarlyView.
In La‐doped CaTiO3, the clustering of La ion and Ca vacancies is clearly observed and the configuration of such defect‐cluster is validated. Combining photoelctronic and dielectric spectroscopy enables the dielectric relaxation process with the charge transfer routes.
