Spinning quantum dots

Phys.org   -   Scientific News Websites

The name 'quantum dots' is given to particles of semiconducting materials that are so tiny—a few nanometres in diameter—that they no longer behave quite like ordinary, macroscopic matter. Thanks to their quantum-like optical and electron...
