Graphene and 2D materials can turn 'Moore's law' into the past

A group of researchers in Manchester (UK), Netherlands, Singapore, Spain, Switzerland, and the United States recently published a new study on a field of computer equipment development commonly known as ' spintronics' , which uses graphene as the foundation for making next-generation electronics.

Recent advances in theory and experimentation, as well as groundbreaking findings in spin electronics research involving graphene and related 2D (2D) materials, have drawn people's attention. into an exciting new field of research and development.

Spintronics is a combination of electronics and magnetism , at the nanoscale and could lead to the introduction of next-generation high-speed electronics. The device spins the solution viable alternative to electronic devices nano (nanoelectronic) beyond the framework of Moore's Law, with the ability to use energy more efficient and less wasteful than devices traditional electronics, which rely on electric charge. In theory, we could make phones and tablets that work with semiconductors and memory chips based on electronic spin.

The research, published in the Review of Modern Physics, focuses on new aspects of heterostructure and the phenomena associated with them.

You probably already know spintronics on laptops and PCs - these devices have been using spintronics in the form of magnetic sensors in the hard drive's reading area. These sensors are also used in the car industry.

Spintronics is a new direction to develop electronic devices, in which both memory devices (RAM) and logic devices (semiconductors) are designed to take advantage of "spin" (rotation), which is part of basic properties of electrons, making them act as tiny magnets, as well as being charged.

Dr Ivan Vera Marun, lecturer at the University of Manchester, said: " The developments related to graphene spintronics, and more broadly, 2D heterogeneous structures, have allowed us to create, transport, and detect. spin information using effects that were previously in graphene alone cannot be accessed . "

" . We believe that in the future, spin transport will be performed in 2D heterogeneous structures, even at room temperature. Such transport will allow the utilization of quantum mechanical properties. of electron wave functions, bring spin into 2D materials for use in future quantum computing devices . "

Controlling spin transport in graphene and 2D materials has been opening promising new applications in electronic devices, especially customized heterogeneous structures - heterogeneous structures. van der Waals - contains many ranges of 2D materials arranged in an orderly controlled manner. This study gives us an overview of the field of graphene spintronics research and clarifies theories and experiments related to this field.

Billions of spintronics devices such as sensors and memory chips are being produced. Every hard drive has an electromagnetic sensor that uses spin currents, and magnetic RAM chips are also becoming more and more popular.

Interesting results have been produced over the past decade in the field of graphene spintronics, and consequently further research has been carried out to expand into new 2D compounds.

Since its discovery in 2004, graphene has opened the door for other 2D materials. Researchers have since been able to use these materials to create rows of 2D materials called heterogeneous structures. They can be combined with graphene to create new design materials, to produce devices that were previously only available in science fiction works.

Professor Francisco Guinea, co-author of the study, said: " The field of spintronics, properties and spin applications in materials has brought a host of new concepts in the study of solids. The fundamental aspect of the motion of spin-carrying electrons is one of the most exciting fields in solid matter physics . "

The identity and properties of new quantum materials with unusual topology electrons and magnetic properties are being studied more and more globally after the concept of topological insulators has been shaped. founded in 2004. Spintronics is at the center of this quest. Because of their purity, durability, and simplicity, 2D materials are the best platform for finding unique topological features related to physics, electronics, and quantum magnetism. .

Overall, the field of spintronics in graphene and related 2D materials is now fast-forward, with graphene spintronics devices such as nano oscillators for applications in communication, space, and communications. High speed radio waves, car radars, and interchip communication applications.
