Scientists from many countries have found that graphene can be used as a basic material for electronic products such as vehicle radar

According to foreign media reports, a group of researchers from Manchester, the United Kingdom, the Netherlands, Singapore, Spain, Switzerland and the United States published a review called spin electronics, which is related to the development of computer devices. In it, they stated that graphene can be used as the basic material for the next generation of electronic products.

Recent advances in theory and experiment studying electron spin transport in graphene and related 2D (two-dimensional) materials have become a fascinating area of ​​research and development.

Spintronics, a combination of nanoscale electronics and magnetism, could allow electronics to advance at a rate that outpaces Moore's law, which states that computer processing power will double approximately every two years and prices will halve. Spintronic devices are more energy efficient and have lower dissipation than conventional electronic devices that rely on charge and current. In principle, we could enable phones and tablets to run on spin-based transistors and memory, greatly increasing speed and storage capacity.

Since its isolation in 2004, graphene has opened the door to other 2D materials. Researchers have used them to create a collection of 2D materials called heterostructures. These materials can be combined with graphene to create new "designer materials" to create applications that previously existed only in science fiction.

This published review focuses on new perspectives arising from heterostructures and their phenomena, including close-range spin-orbit effects, coupled spin pairs, electrical tunability, and 2D magnetism.

Ordinary people have already encountered it on laptops and PCsSpin electronics , such devices are already used in the form of magnetic sensors in the read heads of hard drives, and such sensors are also used in the automotive industry.

Controlled spin transport in graphene and other 2D materials has an increasingly promising future for device applications. Of particular interest are tailor-made heterostructures, also known as van der Waals heterostructures, which consist of a stack of 2D materials in a precisely controlled order.

Hundreds of millions of spintronic devices, such as sensors and memories, are already in production; every hard drive has a magnetic sensor that uses a flow of spins, and magnetic random access memory (MRAM) chips are becoming increasingly popular.

In general, the field of spintronics of graphene and related 2D materials is currently developing towards practical graphene spintronic devices, such as coupled nano-oscillators for applications in space communications, high-speed radio links, vehicular radar, and chip-to-chip communications.
