A group of researchers from Switzerland’s École Polytechnique Fédérale de Lausanne believe this newly designed wire might be the thinnest metallic nanowire ever created; so much so that it can also remain stable at 0 degrees Kelvin.
However, this would be the first time researchers exfoliated one-dimensional materials like carbon nanotubes. This approach created a database of around 78,000 known 3D crystalline structures. If the algorithm is correct it could help in identifying crystals “whose spatial organization of atoms contained natural wire-like threads. It would also calculate precisely how much energy would be required to separate these one-dimensional nanowires from the rest of the baseline crystal, which is critical in determining how viable they would be to actually fabricate,” according to an article inThe team was able to finally bring down the list to 800 visible candidates.
“It’s really interesting because you would not expect an actual wire of atoms along a single line to be stable in the metallic phase,” Cignarella opined. The researchers mentioned their 1D wire could be exfoliated from three distinct crystal sources — NaCuC2, KCuC2 and RbCuC2. “It requires little energy to be extracted from them,” the release explains, “and its chain can be while preserving its metallic properties, which would make it interesting for flexible electronics.
