A 2D 'antenna' boosts light emission from carbon nanotubes

A flat sheet of atoms can act as a kind of antenna that absorbs light and funnels its energy into carbon nanotubes, making them glow brightly. This advance could aid the development of tiny future light-emitting devices that ...

Spectroscopy and theory shed light on excitons in semiconductors

From solar panels on our roofs to the new OLED TV screens, many everyday electronic devices simply wouldn't work without the interaction between light and the materials that make up semiconductors. A new category of semiconductors ...
