Moore’s Law May Be Called Atom’s Law On The New Frontier Of Technology

Posted By on February 20, 2012

Moore’s law states that the number of transistors that can be placed on an integrated circuit doubles every 18 months to two years, and it’s predicted to reach its limit with existing technology in 2020.

But…Cutting the size of a transistor to a single atom may change that concept. Then again, it’s going to take a while to get a quantum computer working at its operating temperature of minus-391 degrees Fahrenheit which is needed to keep it from migrating out of its channel. Oh well, so now you know!

Feb. 20 (Bloomberg) — Scientists have taken a first early step toward escaping the limits of a technological principle called Moore’s Law by creating a working transistor using a single phosphorus atom.

The atom was etched into a silicon bed with “gates” to control electrical flow and metallic contacts to apply voltage, researchers reported in the journal Nature Nanotechnology. It is the first such device to be precisely positioned using a repeatable technology, they said, and may one day help ease the way toward creation of a so-called quantum computer that would be significantly smaller and faster than existing technology.

But, there is a limitation to the latest finding: The atom must be kept at minus-391 degrees Fahrenheit to keep it from migrating out of its channel, the report said. Because of this, the result should be seen as a proof of principle rather than an initial step in a manufacturing process, the researchers said.
