Advanced Science, EarlyView.I‐doping stabilizes the cubic phase of GeTe and generates “electron‐transparent, phonon‐blocking” grain boundary networks while inducing valence‐band convergence. This synergistic structural‐electronic design enables effective electron‐phonon decoupling, achieving an exceptional average zTave of ∼1.62, a peak zT of ∼2.2, and enhanced mechanical ...

Hierarchical Strengthening of Polycrystal-Inspired Lattice Materials [PDF]
, 2022 Architected lattice materials offer excellent specific properties, ideal for high-performance and weight-critical applications. However, high-strength lattice materials also often exhibit a significant and catastrophic post-yielding collapse due to ...

The origin of the boundary strengthening in polycrystal-inspired architected materials
Nature Communications, 2021 Polycrystal-inspired architected materials are found to be high strength and damage tolerant. Here, the authors conduct in-depth work to unravel the mechanism responsible for the hardening phenomenon, in particular the role of polygrain-like boundary in ...

Enhancing Quasi‐Two‐Dimensional Electronic Structure in Bi2O2Se via Chlorine Substitution
Advanced Science, EarlyView.We demonstrate chlorine substitution as an effective strategy to transform Bi2O2Se into an exfoliatable van der Waals superlattice. Key electronic band feature, including indirect bandgap, effective mass is well preserved, while the 2D character of the system is sufficiently enhanced.

Growth of a vortex polycrystal in type II superconductors [PDF]
, 2004 We discuss the formation of a vortex polycrystal in type II superconductors from the competition between pinning and elastic forces. We compute the elastic energy of a deformed grain boundary, which is strongly nonlocal, and obtain the depinning stress ...
