Wafer‐Scale Self‐Limiting Epitaxy of Bernal‐Stacked Single‐Crystal Boron Nitride

Small, Volume 22, Issue 26, 8 May 2026.
Wafer‐scale, single‐crystal Bernal‐stacked boron nitride (bBN) bilayers are grown by flow‐modulated MOCVD, where monoatomic Ni step edges on Ni(111) deterministically direct AB stacking. As an ultrathin interlayer, bBN suppresses interfacial scattering and enables robust, nonvolatile polarization switching in MoS2 channels, offering a scalable platform

Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene

Small, Volume 22, Issue 26, 8 May 2026.
Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

A New Platform for Twistronics: Perovskite Moiré Superlattices Beyond van der Waals

Small Structures
Moiré superlattices have reshaped condensed‐matter physics by enabling twist‐angle engineering of electronic and excitonic states, traditionally in van der Waals (vdW) systems. This Perspective focuses on perovskites as a transformative non‐van der Waals

Förster valley-orbit coupling and topological lattice of hybrid moiré excitons

Communications Physics
Hybrid excitons in moiré superlattices of two-dimensional (2D) semiconductors inherit the electric dipole, strong moiré trapping, and stacking optical selection rules from its interlayer part, whereas the intralayer part is intended for enhancing optical
