Activating Ionic Carbon Nitrides via Epitaxial Dyadic Coupling for Efficient Solar‐Driven H2O2 Generation

Advanced Science, EarlyView.
Epitaxial integration of a C1N1 phase onto KPHI creates a dyadic charge‐transfer nanostructure with strong interfacial electronic coupling. This architecture drives directional electron transfer from KPHI to C1N1, enabling efficient cocatalyst‐free solar H2O2 production.

Van der Waals Heterostructures for Next‐Generation Spintronics: Multiferroic‐Mediated Magnetoelectric Properties

Advanced Science, EarlyView.
As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

High Upper Critical Field and Type II Superconductivity in Epitaxial Cubic W2N Thin Films

Advanced Science, EarlyView.
Superconducting thin films of stoichiometric W2N demonstrate a high upper critical field (Hc2) of ∼ 8.5 T, uncommon among binary transition metal nitrides. This robust superconducting response under high magnetic fields highlights the technological relevance of W2N for superconducting applications, e.g., integrated quantum and cryogenic electronics ...
