Processors in computers should work in the future much faster, because they consist of small components then millionth of a millimeter of silicon instead of carbon. IBM Build Carbon Based Microchip where electrons flow almost unhindered in the chips. IBM researchers in the approach have solved the problem of the contacts.
Nanotubes – tubes composed of hexagonal arranged carbon atoms could replace silicon as basic material for transistors in a few years. Microprocessors and other computer chips consist of billions of transistors. For silicon physical properties is not possible to include more inside the material.
Nanotubes have only a few millionths of a millimetre structure. Even transistors made of carbon have been built in this scale but they have a strong disadvantage so far: The tiny current that works in them, must leave the transistor to flow in a neighborhood. This was possible only with restrictions, because the area had a large electrical resistance.
Fusion of Metal and Carbon – IBM Create Carbon Based Microchip
The American Electronics Group, IBM has now solved this problem as approachable case of study. The researchers have developed a metallurgical process in which carbon and metal atoms in chemically contacts where those two materials are merged. This procedure for the developers “end-bonded contact scheme” named, it allows to be possible without significantly worsening performance of carbon transistors shrink the contacts on ten millionth of a millimeter.
To get computer to improve performance, the processors, the heart of the computer, must include more and more transistors on the same surface. The end of the flagpole is largely achieved in Silicon. The much smaller nanotube transistors take up far less space. Also speed the electrons that ultimately do the computing work much faster through the novel transistors with Silicon structures.
Silicon Structures are Bottle Neck in Transistor Technology
“There is a bottle neck in any advanced transistor technology”, says Dario Gil, Vice President of science & technology in the IBM Research Division. “With the reduction of the transistors the resistance of contacts increases.
“With the new contacting processes believe researchers on the right track to be to resolve the dilemma. “Brings a step further on the road to a nanotube technology within a decade” said Gil.
Nanotubes are still too expensive
Within processors the calculation speed of large computers, for example by search engines and cloud-cluster computers often faster transistors are used. Nanotubes are also create a home to make more powerful batteries, as IBM pointed out. So far there is still no manufacturing process, with the trillions of nanotubes produce in not expensive lots.
