The new tunable graphene device for experiments in exotic physics, Scientists have been looking for ways to make this atomically thin 2D material to work.
Graphene is thinner than a DNA strand, but still 200 times stronger than steel. It is an excellent conductor of electricity and heat and can be accommodated in various forms – from ultra-thin 2D panels to electronic circuits.
Now researchers have used the talents of their graph system to unite not two but three properties: superconductors, isolation and a type of magnet called ferromagnetism.
Multitasking devices can activate new physical experiments, such as faster-generation electronic research such as quantum computer technology. The new tunable graphene device for experiments in exotic physics.
Graphene has great potential in the electronics world. Its atomic structure, combined with strong electronic and thermal conductivity, “can offer unique advantages in the development of next-generation electronic devices and storage.”
The problem is that the magnetic material used in electronics today consists of ferromagnetic metals such as iron or cobalt alloys. Like ordinary magnets, ferromagnetic materials have north and south poles.
When ferromagnetic material is used to store data on a computer’s hard drive, these poles point up or down and represent zeros and bits called.
By applying electrical voltage through the gates of the graphical device, the electron force supplied to the device moves in the same direction as a small car moving along the route. This creates a strong inertia that turns a graphene device into a ferromagnetic system.
Further measurements revealed amazing new properties: the interior of the graph system became not only magnetic, but also insulating; and despite its appeal, its outer edge overflows into an electronic channel that moves without a hitch.

Such properties mark a rare class of insulators known as Chern insulators, the researchers said.
Researchers say: Our findings show that graphene is the ideal platform for studying a variety of physics, from single particle physics to superconductivity and now physics topology to the investigation of quantum phases of matter in 2D material.

The researchers hope to conduct more experiments with their graphene devices to better understand how Chern’s isolation / magnetism and the mechanism behind its unusual properties arise.
