Giant Berry‐phase‐Driven X‐Ray Beam Translations in Strain‐Engineered Semiconductor Crystals

open access: yesAdvanced Materials, EarlyView.
Due to the Berry‐phase effect, X‐rays propagating in deformed crystals undergo large translations, interesting for X‐ray optics applications. Here, the lattice expansion observed upon H irradiation of dilute‐nitride semiconductors is exploited to engineer the deformation landscape of selectively hydrogenated GaAsN epilayers.

Observation of ν = 5/2 Fractional Quantum Hall Effect in Trilayer Graphene Proximitized by V‐Doped WSe2

open access: yesAdvanced Materials, EarlyView.
Even‐denominator 5/2 fractional state in trilayer graphene/V‐doped WSe2 heterostructure, mediated by proximitized magnetism, is demonstrated. An exceptionally high energy gap ∆5/2 (48 K) for the 5/2 state, significantly surpassing previous values in semiconductors and bilayer graphene (∆5/2 < 1 K) is reported.

Active Learning‐Guided Accelerated Discovery of Ultra‐Efficient High‐Entropy Thermoelectrics

open access: yesAdvanced Materials, EarlyView.
An active learning framework is introduced for the accelerated discovery of high‐entropy chalcogenides with superior thermoelectric performance. Only 80 targeted syntheses, selected from 16206 possible combinations, led to three high‐performance compositions, demonstrating the remarkable efficiency of data‐driven guidance in experimental materials ...

Phase Distribution in Quasi‐2D Dion Jacobson Perovskite Dictates Ultrafast Energy Transfer and Directional Charge Transport

open access: yesAdvanced Materials Interfaces, EarlyView.
An efficient charge transfer and energy transfer at heterostructure interfaces is vital for optoelectronics. Quasi‐2D perovskites with varying layer thicknesses can create multiple interfaces, hindering charge transfer and energy transfer. Cesium Iodide (CsI) can help to redistribute these phases strategically, thereby enhancing energy transfer and ...

Inverse Spillover and Dimensionality Effects on Interstitial Hydrogen

open access: yesAdvanced Materials Interfaces, EarlyView.
Interstitial hydrogen behaves distinctly at interfaces compared to the bulk. Vanadium films show proximity‐dependent hydrogen depletion near interfaces–an inverse of hydrogen spillover. Ion beam and resistivity measurements reveal Fe/V‐superlattices have lower hydrogen solubility and higher critical temperature than Cr/V due to proximity‐induced finite
