Mass manufacturing of metasurfaces

The mass production of flat optical devices with sub-wavelength structures could soon be a reality, thanks to a metasurface fabrication technique developed by researchers at A*STAR.

Breakthrough in the search for graphene-based electronics

For 15 years, scientists have tried to exploit the "miracle material" graphene to produce nanoscale electronics. On paper, graphene should be great for just that: it is ultra-thin—only one atom thick and therefore two-dimensional, ...

Wrinkles take the heat

Single atomic sheets of black phosphorus are attracting attention for their potential in future electronics applications. A*STAR researchers have now completed experiments at the nanoscale to unlock the secret of this material's ...

Twisting light to enable high-capacity data transmission

For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. Because germanium is compatible with the silicon used ...

Abright idea for on-demand nanopatterns

Focused electron beams can simultaneously synthesize optically active nanocrystals and pattern them into intricate surface arrays

Hard-to-stretch silicon becomes superelastic

As a hard and brittle material, silicon has practically no natural elasticity. But in a new study, researchers have demonstrated that amorphous silicon can be grown into superelastic horseshoe-shaped nanowires that can undergo ...
