Phosphorene — a single layer of phosphorus atoms — was isolated for the first time in 2014, allowing physicists to begin exploring its properties experimentally and theoretically.

Creating a voltage between them allowed current to flow between the two perpendicular electrodes — separated from each other by just 20 nanometres, through the single phosphorus atom, which acted as a transistor.

John Morton of the University of Oxford and colleagues succeeded by using a half - millimetre - wide crystal of silicon studded with phosphorus atoms.

At the moment, long - term storage has only been demonstrated for large numbers of phosphorus donors — there may be 10 billion phosphorus atoms in the device used for the new study — but McCamey says the technique should apply to the smaller scales needed for practical spintronics.
