Detecting the Six Polytypes of Five‐Layer Graphite
The six possible periodic crystals—so‐called polytypes of Penta layer graphene are identified using Raman, second harmonic, and electric surface potential measurements. The measurements reveal the polytypes’ abundance, relative stability, and annihilation dynamics, crucial for future multiferroic SlideTronic applications.

Lithography‐guided intercalation creates a proximitized 2D superconducting Ga layer under graphene Hall bars via liquid‐metal intercalation. The image shows a Hall bar where Ga atoms from the liquid phase enter through patterned intercalation channels beneath quasi‐freestanding bilayer graphene, forming a confined 2D metal that demonstrates ...

By tracking bulk carrier diffusion both vertically and laterally, this study links photoluminescence behavior to crystal quality in CsPbBr3 γ‐ray detectors. Vertical diffusion governs spectral redshift, with high‐quality crystals exhibiting superior transport, while two‐photon microscopy reveals microscale defects that hinder diffusion in low‐quality ...

A molecular motor with four‐state dynamic chirality is integrated into liquid crystals, enabling quadruple sequential helix inversions and high helical twisting power. Due to high motor efficiency, the supramolecular helicity can be controlled by near‐infrared light via upconversion nanoparticles, resulting in a robust, multistate, photoresponsive soft

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