Researchers master self-assembly of novel nanodots
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.
