Metasurfaces: Tiny tech with big potential

Imagine manipulating light with ultra-thin, flat sheets instead of bulky lenses and mirrors. That's the promise of metasurfaces, a nanostructure technology that can twist and bend light in ways never before possible.

Illuminating the unavoidable imperfections of nanostructures

A new study by a collaborative team from the University of Twente and the e-Science Center in Amsterdam compares the transmission of light through a utopian model with a real 3D nanostructure. These nanostructures are integral ...

World's first micromachine twists 2D materials at will

Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" ...

Quantifying spin in WTe2 for future spintronics

A RMIT-led, international collaboration published this week has observed large in-plane anisotropic magnetoresistance (AMR) in a quantum spin Hall insulator and the spin quantization axis of the edge states can be well-defined.

Researchers move closer to controlling two-dimensional graphene

The device you are currently reading this article on was born from the silicon revolution. To build modern electrical circuits, researchers control silicon's current-conducting capabilities via doping, which is a process ...

Spintronics: Exotic ferromagnetic order in two-dimensions

The thinnest materials in the world are only a single atom thick. These kinds of two-dimensional or 2D materials—such as graphene, well-known as consisting of a single layer of carbon atoms—are causing a great deal of ...
