IBM scientists have developed the smallest electronic logic circuit for computers - actually a chip - in the world. It occupies a trillionth of a square inch. The tiny electronic circuit consists of carbon monoxide molecules, on a copper surface. The molecules are the tiny transistors, like those embedded in computer chips, but there is no wiring between them.
It is possible that this development will lead to the construction of computer chips of a completely new type, which will also be found in cell phones and other electronic equipment in the future - only in ten years or maybe more.
The tiny electronic circuit uses an idea that originates from dominoes and billiards: when an external force hits one ball, for example, a series of events begins and the ball hits the ball and pushes them forward (in dominoes: when one stone starts to fall and sweeps after it in a certain order and at an increasing rate, all the rest).
How tiny the electronic circuit is, can be learned from the following figure: 190 billion of it is squeezed into the eraser at the end of the pencil. It is 260 thousand smaller than the usual computer chip.
IBM said that the molecular electronic circuit should replace the circuits found in computer chips - semiconductors on a silicon substrate, which exist today. The research team from California noted that at this stage, the logic circuit made it possible to perform not many calculations, but they were achieved under restrictive conditions: in a vacuum (vacuum) and at a temperature close to absolute zero (minus 273 degrees). More years of development will be required before it will be possible to generalize the important technological innovation, in computers.
