The graphene is a material discovered a couple of years ago, and it’s one of the most important materials in physics. This material has enourmous implications in nanotechnology, and could lead to the development of the next-gen devices. After receiveing numerous praises thanks to its properties, graphene is pushing the boundaries once more. According to a research at the Abdus Salam International Center for Theoretical Physics in Trieste, Italy, the graphene’s electrons are “behaving like a nearly perfect liquid.”
Graphene is a form of carbon, and one sheet of graphene is only one atom thick. In a material electrons collide differently depending on the temperature, however, graphene’s electrons are behaving really weird. Graphene’s electrons are very turbulent, but have a low viscosity and due to this property, the graphene is nearing the so-called “quantum critical point.” This poing defines the fact that a material is breaking the laws of physics.
The researchers said that the graphene is a really weird material as a block of ice is melting only withing a temperature range, while the graphene’s electrons can manage a transition to a liquid at a very wide temperature range. Although the graphene should act like a gas, it acts like a soup, researchers say. Also, the electric resistance of a random material is not changing when changing voltage, however, the graphene doesn’t care about this property.
Another fact that the physicist noticed is that the Coulomb interactions are nomally ignored when graphene is studied, but these new discoveries show that the electrons of a graphene are highly interacting therefore Coulomb interactions shouldn’t be ignore from now on.
This is nothing new as there are other examples of weird materials who behave like a nearly perfect liquid. Quark-gluon plasma, and ultra-cold Lithium atoms are the previous two materials where this phenomenom was noticed.
