Following graphene, the dimeric "alkenyl" character is refilled with new members, this time borosilicate. Recently, some scientists have discovered that boron, the chemical element No. 5 in the periodic table, may form a single-layer planar atomic structure similar to graphene. Scientists call it Borphene.
Scientists from the US Department of Energy's Argonne National Laboratory, Northwestern University, and the State University of New York at Stony Brook have for the first time created two-dimensional boron, a material with a single atomic thickness called "boron."
According to the introduction of Science in the 18th, scientists have been interested in the unique properties of this single-layer two-dimensional material, especially its electronic properties. Boron is an unusual material because it exhibits many metallic properties at the nanoscale, while three-dimensional boron or bulk boron are only non-metallic semiconductors. Because borax is both metallic and atomic, it has a wide range of applications from electronics to photovoltaics.
Similar to the “neighbor†carbon elements on the periodic table, boron is often referred to as a “isomorphic body†with different “facesâ€. Graphite is made up of many two-dimensional layers that can be “teared apart†by the entire layer, but for two-dimensional borosilicates, it does not have such properties. Nansen Gouldinger, a nanoscientist who led the research, said: "Bornene is very interesting. It is different from previous two-dimensional materials and does not appear naturally."
Although 16 orthotopics of boron have been identified, scientists have never produced a single monolayer of borole. Researchers say this is an exciting new material that has yet to be discovered and explored.
“This material is very beautiful,†says Lai-Sheng Wang, a professor of chemistry at Brown University. “It has the perfect hexagonal symmetry we are looking for. The hole in this material is very meaningful, indicating that the theory of boron plane structure is correct."
The atomic configuration of boron at the nanoscale is unusual. When other two-dimensional materials look smooth, borosilicate looks like corrugated cardboard, depending on how the atoms combine. This structure determines the directionality of its conductive properties, which is rare in other two-dimensional materials. Furthermore, based on theoretical predictions of the material, it is also likely to have a higher tensile strength.
It should be pointed out that the discovery and synthesis of borosilicates actually utilizes computer simulation tools.
