One-dimensional, only length; Two-dimensional, that is, a flat world, only length and width; Three-dimensional, with length, width and height, is a three-dimensional world, and it is also the world
that we personally feel and see with the naked eye.
In the three-dimensional world of reality, whatever is three-dimensional
.
However, scientists have used graphene and tellurium to make theoretically stable one-dimensional wires
.
First, graphene is a hexagonal flat film with a honeycomb lattice paved by a single carbon atom, and because it is only one carbon atom thick, it can theoretically be called a two-dimensional object
.
Because it is currently the thinnest and hardest substance in the world, can not be cut, scientists bend it into a tube, put tellurium in the middle, by reducing the diameter of the graphene tube, so that the tellurium element is gradually squeezed into a stable linear structure composed of a single atom, although this linear structure is still 1 atom wide and high, but it is already a theoretical one-dimensional, therefore, the wire produced is also "one-dimensional tellurium wire"
.
It is reported that the "one-dimensional tellurium wire" is made by researchers at the University of Cambridge in the United Kingdom, using carbon nanotubes with a diameter between 0.
7 and 1.
1 nanometers (nm) to make a "one-dimensional tellurium line", which is only one
ten-thousandth of the diameter of a human hair.
The results of the study have been published in ACS Nano
.
Why did you choose tellurium as a conductor? Tellurium is an element of organs, and usually it exhibits a physical behavior of semiconductors, but in a tight enclosed space, its physical behavior behaves more like metal, like a wire
.
By changing the diameter of the carbon nanotubes, scientists can control the physical properties of tellurium
