Researchers constraint properties of graphene transistors utilizing pressure as the Columbia University researchers have evolved a technique to engineer the electrical conductivity of graphene with contraction conducting the material closer to bring a feasible semiconductor for utilization in present day’s electronic gadgets and devices.
Matthew Yankowitz, a postdoctoral research scientist in Columbia’s physics department and first author on the study said that Graphene is the best electrical conductor in the world. The issue arises from the fact that it is an absolute marvel for conducting electricity, and we do not know the way to stop it competently.
Our work manifests for the premiere time a path towards realization a technologically pertinent band gap in graphene without undermining its quality. Besides if correlated to other captivating combinations of 2D materials, the technique being utilized now could be used in a novel nascent phenomena like magnetism, superconductivity, and more.
The atypical electronic properties of graphene, a two-dimensional (2D) material comprised of hexagonally-bonded carbon atoms, has been an issue of discussion in the physics community since its discovery more than a decade ago. Graphene is the strongest, thinnest material known to exist. It also happens to be a superior conductor of electricity, the distinctive atomic disposition of the carbon atoms in graphene permits its electrons to effortlessly traverse at extremely high velocity with no chance of scattering reducing valuable energy that is not stored in other conductors.
Cory Dean, assistant professor of physics at Columbia University and the study’s principal investigator said that graphene research leads to conjecturing a way to maintain all the good points of graphene busty also generate a band gap, an electrical on-off switch.
