“Perfect” single-atom transistor created.
Researchers at an Australian University have created a working transistor out of a single atom of phosphorus, placed on a silicon crystal. The microscopic device even has tiny visible markers etched onto its surface so researchers can connect metal contacts and apply a voltage.
The result - published here - is a huge step towards future quantum computers able to process complex equations which are so far beyond the reach of even the fastest supercomputers. The research will also enable the continuation of ever smaller transistors in accordance with (or even exceeding) Moores Law, which would mean that all transistors reach single-atom level by 2020.
