Double Helical Plasmonic Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Emergence of Local Magnetic Moment in Ternary TaWSe2 Single Crystal via Atomic Clustering

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates local magnetic moments in ternary TaWSe2. Triangular Ta clusters with consistent shapes are identified through STM/S, and DFT calculations. These clusters induce localized strain, generating magnetic moments at the cluster corners. Magnetic measurements confirm a magnetic anomaly at ∼50 K.

Ferroelectricity in Single‐Crystalline BaTiO3 Nanodisks on Silicon

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectricity is studied in 20 nm thick single crystalline BaTiO3 nanodisks when scaling their diameter from ≈ 400 down to 100 nm. For 100 nm diameter, the vertical polarization component adopts three distinct patterns, and the lateral one shows a rotational invariance in‐plane, suggesting a combination of center‐type and flux‐closure domains.

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

open access: yesAdvanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.
