Not-so-spotty material breakthrough

Abstract:
Using pulsed lasers, researchers have coaxed the metal nickel to self-assemble into arrays of nanodots each spot a mere seven nanometers (seven billionths of a meter) across one-tenth the diameter of existing nanodots.

Because the method works with a variety of materials and may drastically reduce imperfections, the new procedure may also bolster research into extremely hard materials and efforts to develop ultra-dense computer memory.

The researchers are working with an industry partner to apply the technique to development of next-generation light-emitting diodes (LEDs) the small, bright lights seen in traffic signals and luxury automobile brake lights. The experimental LEDs are already more efficient than existing devices, potentially lasting decades and using a fraction of the power of fluorescent bulbs.
