What it is
A functional transistor whose channel is a single phosphorus atom placed with atomic precision in a silicon crystal using a scanning tunnelling microscope. It shows that an electronic device can be built at the smallest scale of matter.
Published in Nature Nanotechnology in 2012. It is a laboratory device, not an industrial component.
What it led to
- fabrication of silicon qubits at the atomic scale
- single-atom electronics
- phosphorus-based quantum computing programmes
