Researchers Create Transistor Mini Size

A number of Australian scientists claim to have created an atom-sized transistors. This discovery could be the start of the next generation of nano technology.

Microscopic device was made of a single phosphorus atom embedded in the silicon which is the "gate" to control the flow of electricity and the metal contacts are also sized atom.

The study, led by Martin Fuechsle proved that it is possible to position a single phosphorus atom in silicon.

"Previously, atom-sized transistors have been made. However, it was just a coincidence," said Michelle Simmons, Director of the Center for Quantum Computing and Communication of the University of New South Wales, Australia.

A silicon crystal is manipulated at the molecular level by using a microscope a very fine tipped metal, the resulting chemical reaction, is used to unify the atoms on the surface of the silicon transistor was. The devices operate only in a matter of minutes and in extra cold temperatures from liquid helium.

Microchip development during the last 50 years is proof of Moore's Law is found by Gordon Moore, founder of the Intel chip. He predicts that the number of transistors on a chip will double every 18 months. However, with the discovery of atom-sized transistors, Moore's opinion would very likely deny.
