Scientists have discovered new and amazing properties in the element Bismuth. These scientists who made this amazing discovery are Maia G. Vergniory, Ikerbasque researcher at DIPC and UPV/EHU associate. The researchers have found out that Bismuth exhibits properties unlike other conductors of electricity.
In their research which has since been featured on the Nature magazine, they explain how Bismuth has unique conduction abilities compared to other conductors. Bismuth is now regarded in the class of high order conductors.
In order to make you understand why Bismuth is a special conductor, we have to first understand how other elements conduct. First, we have to understand that, topological conductors are elements which conduct electricity on the surface but are insulators on the core.
Bismuth is unique such that it conducts electricity on the edge of its crystal rather than on the surface like other conductors. This means that current flow is efficient and consistent and the flow is higher in frequency compared to lower order conductors.
Scientists have long predicted the existence of such an element but there had been no discoveries made of such. According to the theoretical view of the research, elements that conduct electricity in this way are far better conductor of electricity compared to topological conductors. The crystal will allow for conduction of electricity at a lower temperature since the current will be simply passed on to the edge of the next crystal.
Bismuth is still a topological conductor but with elevated properties. These properties will allow it to be incorporated in the making of high-end electrical appliances and devices. This discovery also ensures that no current is lost in the process of conduction. If the world adapts to the use of this element, there is going to less loss of current in the process of conducting electricity.
The research’s results were arrived at by using symmetrical arguments, topological indices, first principle calculations, and topological quantum chemistry. The experiment was then used Josephson interferometry to show the universal topological contribution to the electronic transport.
In normal topological conductors, the current of topological electrons can be interfered by a reduction in temperature. This is not the case with Bismuth as the current will flow consistently given the material is not broken or the links cut off.
This discovery leaves much to be researched and increases the ability of Bismuth. If adapted correctly, it can be used to enhance conduction in devices that we use therefore their efficiency.
