Self‐Recovery of Carbonate‐Contaminated Strontium Titanate (100) Vicinal Surfaces Imaged by Tip‐Enhanced Raman Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Strontium titanate, a widely used perovskite material, undergoes changes in surface properties under CO2 adsorption. This study demonstrates a self‐regeneration process where strontium carbonate gradually delaminates, leaving a TiO2 termination. The findings, supported by optical near‐field spectroscopy and density functional theory, have broad ...

Zinc Chalcogenide Based Shell Layers for Colloidal Quantum Wells

open access: yesAdvanced Materials Interfaces, EarlyView.
A new synthetic route is developed for the synthesis of CdSe/ZnSe/ZnS multi‐shell nanoplatelets (NPLs) with emissions between 615 and 630 nm and photoluminescence quantum yields up to 90%. Control over the lateral size of the starting CdSe core enabled the narrowing of the emission linewidth to 20 nm.

Emergent Ferromagnetism at LaFeO3/SrTiO3 Interface Arising from a Strain‐Induced Spin‐State Transition

open access: yesAdvanced Materials Interfaces, EarlyView.
Strain at the LaFeO3/SrTiO3 interface induces spin‐state disproportionation, creating a checkerboard pattern of low‐ and high‐spin Fe3+ ions. This unusual configuration leads to interfacial ferromagnetism in an otherwise antiferromagnetic insulator. Using electron microscopy, spectroscopy, and density functional theory, this work reveals a new route to

An Atomic‐Scale View at γ’‐Fe4N as Hydrogen Barrier Material

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates the efficacy of γ’‐Fe4N nitride layers, formed via gas nitriding, as hydrogen permeation barriers. Advanced characterization, hydrogen permeation analysis, and DFT calculations reveal a 20 fold reduction in hydrogen diffusion at room temperature.
