Music stored in smallest stable rewritable atomic memory

Using a Scanning Tunneling Microscope (STM), we are now able to reliably remove and replace single atoms of hydrogen on a silicon surface. These new techniques allow us to store binary information, used in modern computers, with just one atom representing each bit, or unit, of information. The stored information can be changed by adding or removing atoms to write new information.

Atomic Silicon Quantum Dot Wires

Atomic Quantum Dots enable a revolutionary approach to computation. It has been discovered that single silicon atoms act as "quantum dots", enabling control over single electrons, thereby consuming miniscule power. This new control over electrons can be put to use in various ways. For example, the "QCA" (quantum cellular automata) mechanism proposed by Craig Lent and co-workers at Notre Dame provides an architecture for an extremely low power computer.

Time-resolved dopant charge dynamics in silicon

This animation represents an electrical current being switched on and off. Remarkably, the current is confined to a channel that is just one atom wide. Also, the switch is made of just one atom. When the atom in the centre feels an electric field tugging at it, it loses its electron. Once that electron is lost, the many electrons in the body of the silicon (to the left) have a clear passage to flow through. When the electric field is removed, an electron gets trapped in the central atom, switching the current off.
