It was created by placing a crystal of silicon and phosphorus atoms and a number of '10,000 times more' thinner than a hairThe smallest thread in silicon - which measures four atoms in width and height of an atom - were made at the University of New South Wales in Sydney, Australia, and illustrated in the journal Science.
According to the study, despite the extremely small diameter - 10,000 times thinner than a human hair - this theme has outstanding electrical properties equal to the same electrical current carrying capacity of copper.
The researchers tested the electrical resistivity of their discovery - that the measure of the ease with which electric current can flow - proving that it does not depend on the width of the wire. This means that even for the "nanowires" Ohm's law applies.
Achieved by placing a silicon crystal many atoms of phosphorus, lined up in long chains and separated by only a millionth of a millimeter, the world's smallest thread opens up the possibility of connecting the components of the atomic-scale quantum computers. The thread of silicon could in fact be used for addressing individual atoms that form the computational units of these machines of the future.
