Wen/Chen Gencarbon exists in various forms
.
Among them, graphene with a thickness of only one atomic layer is the thinnest material known.
In graphene, each carbon atom is connected to three adjacent carbon atoms to form hexagons arranged in a honeycomb network
.
The unique characteristics of graphene also make it an extremely exciting candidate material in future applications such as electronics and high-tech engineering
.
Now, a research team from Europe claims that they have developed a new non-benzene-based carbon allotrope, which has certain similarities with graphene.
At the same time, a lot of differences are maintained
.
The work started by placing carbon-containing molecules on a very smooth gold surface, where the researchers let them form two mirror-image types of chains (like left-handed or right-handed)
.
Although graphene will bind different chains together, in new materials, only chains of the same type will be joined together
.
So the researchers were able to see the honeycomb pattern, and also observed that it formed squares and octagons
.
After confirming the structure of the new material with a high-resolution scanning probe microscope, the research team named it Biphenylene Network and found that its electrical properties are very different from graphene
.
This network is atomically thin, like graphene, but composed of squares, hexagons and octagons, forming an ordered lattice
.
They confirmed the unique structure of this network with a high-resolution scanning probe microscope.
Interestingly, they found that its electronic properties are very different from those of graphene
.
In contrast to graphene and other forms of carbon, this new type of non-benzene carbon allotrope has metallic properties
.
The narrow stripes of only 21 atoms wide in the network already behave like a metal, and graphene is a semiconductor of this size
.
The researchers said that these stripes can be used as wires for future carbon-based electronic devices
.
In addition, this new type of carbon network can also be used as a superior cathode material for lithium-ion batteries.
Compared with the current graphene-based materials, it has a larger lithium storage capacity. .
Currently, the researchers have introduced their new findings in the journal Science
.
And named his newly discovered title "Biphenylene network: A nonbenzenoid carbon allotrope", that is, "Biphenylene network: a nonbenzenoid carbon allotrope"
