Technique turns computer chip defects into an advantage
Physicists at Ohio State University have discovered that tiny defects inside a computer chip can be used to tune the properties of key atoms in the chip.

The technique, which they describe in the journal Science, involves rearranging the holes left by missing atoms to tune the properties of dopants -- the chemical impurities that give the semiconductors in computer chips their special properties.
