The circuit is built from a carbon nanotube molecule: a collection of carbon atoms that make up a row of atomic circles connected to each other in the molecule in the structure of a "tube". This molecule is a hundred thousand times smaller than the thickness of a human hair

IBM scientists were able to build and demonstrate the operation of the first computer circuit
In a world based on a single molecule. Continued development of this could lead
In the future for the construction of smaller and faster computers, with current consumption
lower than that of everything sold today.
The IBM team built a "NOT gate" - one
Of the three logic circuits that form the basis of every computer today. the circle
Constructed from a carbon nanotube molecule: a collection of constituent carbon atoms
A row of atomic circles connected to each other in a molecule in the structure of a "pipe".
This molecule is a hundred thousand times smaller than the thickness of a human hair.
Carbon nanotubes are currently the leading candidate to replace silicon
currently used to build computer chips, when the miniaturization processes will arrive
In silicon chip technology, to the limits of physical feasibility -
The expected barrier in 10-15 years. IBM scientists believe that electronics
of nanotubes will lead to the progress of miniaturization processes and a jump in intensities
Computing, on a scale that is hard to imagine today.
IBM's new development was presented at the meeting of the American Chemical Society,
which took place this week in Chicago.
This is the second scientific breakthrough reported this year by IBM in the field
The use of carbon nanotubes to produce tiny electronic components.
In the April issue of the scientific journal Science, the same team reported on
Success in building transistors in the structure of a nanotube, while bypassing
The need for strict separation between metallic nanotubes and nanotubes
Semiconductor. It is these transistors that were used to build the circuit
The complete logic, which the researchers revealed this week.
IBM scientists used nanotubes to build an answer logic gate
Negative - also known as "turning current". The scientists coded all the logic
of the current reversal function along the length of a single carbon nanotube, while they
Building the world's first logic circuit on a single molecule.
In the digital-binary world that operates in terms of "zero" and "one", a gate
A negative answer logic turns every “”1 into a “”0 and every “”0 into a “”1 all
inside a computer chip. The processors at the heart of every computer are a combination
A large and complex set of "no" gates with two additional basic functions:
"Also" and "Or" &#;8211 which perform other calculation operations.
