Caption: An atomic-scale memory chip, made by removing individual atoms from a silicon wafer, has been created by a team of scientists led by Franz Himpsel, professor of physics. The feat, reported in the journal Nanotechnology, represents a first crude step toward a practical atomic-scale memory where atoms of silicon would represent the binary 1s and 0s that computers use to store data.
