When two layers of graphene or of other two-dimensional (2D) materials are stacked on top of each other with a small angle misalignment, the crystal lattices produced by each layer are spatially 'out of synch'. This results ...
When two similar atomic layers with mismatching lattice constants—the constant distance between a layer's unit cells—and/or orientation are stacked together, the resulting bilayer can exhibit a moiré pattern and form ...

Two-dimensional (2D) materials and van der Waals (vdW) heterostructures are flexible materials with distinct atomic layers beyond traditional units of lattice-matching requirements. Nevertheless, the 2D van der Waals structures ...
A team of international physicists including Jennifer Cano, Ph.D., of Stony Brook University, has created a new material layered by two structures, forming a superlattice, that at a high temperature is a super-efficient insulator ...

Nanoparticle superlattice films that form at the solid-liquid interface are important for mesoscale materials but are challenging to analyze on the onset of formation at a solid-liquid interface. In a new report on Science ...
A recent study from the labs of James Hone (mechanical engineering) and Cory Dean (physics) demonstrates a new way to tune the properties of two-dimensional (2-D) materials simply by adjusting the twist angle between them. ...
