Atomic-scale tailoring of graphene approaches macroscopic world

Properties of materials are often defined by imperfections in their atomic structure, especially when the material itself is just one atom thick, such as graphene. Researchers at the University of Vienna have now developed ...

Trions exhibit novel characteristics in moiré superlattices

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 ...

Novel liquid crystal metalens offers electric zoom

Researchers from Cornell University's School of Applied and Engineering Physics and Samsung's Advanced Institute of Technology have created a first-of-its-kind metalens—a metamaterial lens—that can be focused using voltage ...

Compositional dependence of perovskite nanocrystal properties

Researchers from Skoltech and Ludwig Maximilians-Universität (LMU) in Germany have studied the fundamental properties of halide perovskite nanocrystals, a promising class of optoelectronic materials. Using a combination ...

Shining light on two-dimensional magnets

Atomically thin van der Waals magnets are widely seen as the ultimate compact media for future magnetic data storage and fast data processing. Controlling the magnetic state of these materials in real-time, however, has proven ...

Hexagonal boron nitride's remarkable toughness unmasked

It's official: Hexagonal boron nitride (h-BN) is the iron man of 2D materials, so resistant to cracking that it defies a century-old theoretical description engineers still use to measure toughness.
