2D Heterostructure Non-volatile Spin Memory Technology

在现代社会，随着信息技术的使用迅速增加，有必要开发新的非易失性、更快、节能的电子产品。自旋电子技术为实现这一目标开辟了有希望的途径。然而，基于传统材料的设备在消费电子产品中的应用效率仍然太低。在此，我们建议基于新兴的原子薄二维（2D）量子材料开发一种新的节能自旋电子存储器件平台，用于下一代存储技术。二维拓扑自旋轨道材料可以产生巨大的电流诱导自旋极化，而室温二维磁体则为磁的电控制提供了前景。所提出的由二维拓扑自旋轨道材料和二维磁体组成的范德华异质结构自旋电子器件将以低电流密度和超快的磁化开关速度实现非常有效的自旋轨道扭矩（SOT）功能。全二维多功能SOT将在自旋电子学和二维材料之间提供强大的协同作用，并将这项研究从TRL2带到4。我们将采用新颖的方法来控制它们的SOT性能-通过层之间的扭转角，拓扑方面，晶体对称性，邻近相互作用和强电场效应。为了实现这一具有挑战性的目标，该项目汇集了开拓性和世界领先的实验和理论研究人员以及欧洲自旋电子学和二维材料领域的一家公司。全2d SOT器件单元的最终演示将融合自旋电子学和涡旋电子学领域，允许物理和电气调谐参数，以实现对器件功能的增强控制。这些发展将为低功耗、非易失性、超快和可扩展的数据存储和处理设备以及可能的新的基于自旋的计算范式和架构提供开创性的2D SOT技术。

In modern society, as the use of information technology is rapidly increasing, it is necessary to develop new non-volatile, faster, and energy-efficient electronics. Spintronic technologies open promising routes to achieve this. However, devices based on conventional materials are still too inefficient for applications in consumer electronics. Here, we propose to develop a new energy-efficient spintronic memory device platform based on emerging atomically-thin two-dimensional (2D) quantum materials for the next generation of memory technologies. The 2D topological spin-orbit materials can generate a giant current-induced spin polarization, whereas room temperature 2D magnets provide the prospective of electric control of magnetism. The proposed van der Waals heterostructure spintronic devices consisting of 2D topologicalspin-orbit materials and 2D magnets will enable exceptionally efficientspin-orbit torque (SOT) functionality with low current densities and ultrafast magnetization switching speed. All-2D multifunctional SOT will provide a strong synergy between spintronics and 2D material and take thisresearch from TRL2 to 4. We will employ novel methodsto control their SOT properties – by the twist angle between the layers, topological aspects, crystal symmetries, proximity interaction, and strong electric field effects. To achieve this challenging goal, this project brings together pioneering and world-leading experimental and theoretical researchers and a company in the field of spintronics and 2D materials in Europe. The ultimate demonstration of all-2D SOT device units will merge the field of spintronics and twistronics, allowing for physical and electrical tuning parameters to achieve enhanced control over the device functionalities. These developments will enable groundbreaking 2D SOT technologies for low-power, non-volatile, ultrafast, and scalable data storage and processing devices and possibly new spin-based computing paradigms and architectures.
