Two-dimensional (2D) materials and their heterostructures for constructing all-2D spintronic devices enable fast operation compared to conventional materials and operate at very low current densities.
As the most studied 2D material, graphene is used to strengthen polymers, concrete, and paints, and is also expected to replace silicon in semiconductors. Products containing graphene now exist in everything from tennis rackets, helmets, grease oils, mobile phones, and electric cars to healthcare and aerospace. However, research and development of other his 2D materials is still in the early stages.
world-leading researchers
The 2D Heterostructure Nonvolatile Spin Memory Technology Project, also known as 2DSPIN-TECH, uses 2D quantum materials and their heterostructures to develop spintronics-based memory devices. To achieve this, the project brings together Europe’s pioneering and world-leading experimental and theoretical researchers and companies in the field of spintronics and his 2D materials.
This project aims to exploit the spin degree of freedom of electrons to provide a breakthrough in next-generation magnetic random access memory (MRAM) technology using atomically thin 2D material heterostructures. This device architecture incorporates a 2D spin-orbit material (2DSOM) and a 2D ferromagnet (2DFM) in a van der Waals (vdW) heterostructure to exploit the fundamental interaction between charge, spin, and orbital degrees of freedom. To do. It is expected to provide high-speed, low-power, and reliable memory solutions. These developments open an opportunity for Europe to return to the memory market.
“2DSPIN-TECH goes far beyond what has been studied in the Graphene flagship spintronics work package by exploring more comprehensive mechanisms and all-2D devices elaborated with new materials,” says the project. Coordinator Quantum Professor Saroj Dash said. Device Physics at Chalmers University of Technology.
sustainable IT solutions
This project offers great potential for new and more sustainable solutions for the future use of information technology.
“2D magnetic materials are atomically thin and have unique magnetic properties, making them highly sustainable and enabling the development of new energy-efficient and ultra-fast applications for sensors and advanced magnetic memory and computing concepts. This makes them promising candidates for various technologies,” says Professor Saroj Dash.
Beyond memory devices, the technology developed at 2DSPIN-TECH can be used in quantum computing as a means to create and manipulate qubits, the basic building blocks of quantum computers. Such non-volatile memory technology may also provide a more secure way to store sensitive personal and organizational information.
