Silicon atoms play a bit part
12 July 2002

A memory that stores a 'bit' by the presence or absence of a single
silicon atom has been developed by physicists at the University of
Wisconsin-Madison in the US and the University of Basel in Switzerland.
Franz Himpsel's team created the device - made from silicon and gold -
which has a storage density of 250 terabits per square inch (R Bennewitz
et al Nanotechnology 13 499).

- Yay! Doesn't sound very practical yet, but we are getting there one
bit at a time...
