Graphene Is a Tunable Plasmonic Medium
June 20, 2012 — With a beam of infrared light, scientists have sent ripples of electrons along the surface of graphene and demonstrated that they can control the length and height of these oscillations, called ... > full story -
Taming Light With Graphene
June 20, 2012 — Scientists have visualized the trapping and confinement of light on graphene, making a sheet of carbon atoms the most promising candidate for optical information processing on the nano-scale, optical ... > full story -
Extremely Thin Perfect Nanotube Could Be Grown One Meter Long
June 19, 2012 — At the right temperature, with the right catalyst, there's no reason a perfect single-walled carbon nanotube 1/50,000th the thickness of a human hair can't be grown a meter long. Scientists have ... > full story -
Relocating LEDs from Silicon to Copper Enhances Efficiency
June 14, 2012 — Chinese researchers have succeeded in transferring gallium nitride (GaN) light-emitting diodes (LEDs) grown on a layer of silicon to a layer of copper. In comparison with LEDs on silicon substrates, ... > full story -
