Unusual Van der Waals Magnetoresistance in Stacked Ferromagnetic Fe3GeTe2: The Role of Atomically Sharp Interfaces

open access: yesAdvanced Science, EarlyView.
Angular‐dependent magnetoresistance in stacked Fe3GeTe2 reveals high‐order UAMR that defies spin‐current‐based interpretations. Instead, it originates from internal electric fields at atomically sharp interfaces (ASI), in excellent agreement with two‐vector MR theory.

Controlling Twisted Angles in Directly Grown MoS2 Bilayers via Tilt Grain Boundary Engineering

open access: yesAdvanced Science, EarlyView.
In this study, the stacking configurations and the growth mechanism of twisted bilayer (TB) MoS2 are systematically investigated, revealing that the relative rotation angle between the two layers is guided by the tilt grain boundary (GBs) of the bottom layer.

Chemically‐Disordered Transparent Conductive Perovskites With High Crystalline Fidelity

open access: yesAdvanced Science, EarlyView.
Kinetically arrested, chemically disordered perovskite thin films exhibit exquisite crystalline fidelity, broad IR–UV transparency, and low resistivity, despite incorporating five mismatched 3d–5d cations, including Cr and W. This study unites electronic correlation, cation diversity, valence complexity, and disorder—enabling new transparent conductors

Manipulating the Hydrogen‐Associated Insulator‐Metal Transition Through Artificial Microstructure Engineering

open access: yesAdvanced Science, EarlyView.
Establishing an unobstructed conduit for hydrogen diffusion via the artificial design of material microstructure associated with boundary configuration and crystal orientation offers a powerful tuning knob for extensively accelerating the proton mobility and enhancing electronic phase modulations, thereby advancing the high‐speed protonic device ...

Superconductivity in Hourglass Dirac Chain Metals (Ti, Hf)IrGe

open access: yesAdvanced Science, EarlyView.
We report the discovery of ternary germanide superconductors MIrGe (M = Ti, Hf) that host hourglass Dirac chains protected by nonsymmorphic symmetry. These compounds exhibit bulk type‐II superconductivity with fully gapped states and preserved time‐reversal symmetry, as confirmed by µSR measurements.

High‐Temperature Superconductivity of Thermodynamically Stable Fluorite‐Type Hydrides at Ambient Pressure

open access: yesAdvanced Science, EarlyView.
Fluorite‐type AXH8 hydrides comprise H8 units formed by small‐radius X elements and hydrogen, linked into a 3D weak covalent network. Large‐radius A atoms act as electron donors, stabilizing the lattice and enhancing delocalization. A linear correlation between minimum ELF at H8 connections and electron–phonon coupling λ underpins their ...
