Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Tailoring Symmetry Breaking in Engineered van der Waals Superlattices
We pioneer a scheme to tailor superpotentials in graphene based on intrinsic substrate electronic orders rather than twist angle. The resulting superpotential folds graphene's Dirac cones to either Γ$\Gamma$ or K‐points, leading to distinct symmetry behaviors.

Moiré superlattice effects on interfacial mechanical behavior: A concise review
The moiré superlattice, arising from the interface of mismatched single crystals, intricately regulates the physical and mechanical properties of materials, giving rise to phenomena such as superconductivity and superlubricity. This study delves into the

Ultrathin Freestanding BiFeO3 Membranes Grown by Pulsed Laser Deposition
Ultrathin freestanding BiFeO3 membranes down to five‐unit cells are realized by pulsed laser deposition using a water‐soluble Sr3Al2O6 sacrificial layer. Strontium diffusion is revealed to drive the spontaneous formation of an Aurivillius‐like phase, while ultrathin SrRuO3 interlayers suppress interfacial intermixing, preserve polar tetragonality, and ...
