Exploiting spin transport in 2D materials for computation beyond Moore's law

像石墨烯这样的二维(2D)材料，是一种单层碳原子，表现出非凡的电子和热学性能，使它们有望成为未来的电子设备。最近，由于将这些材料的单层堆叠在三明治结构中的可能性，人们对这些材料的兴趣更加浓厚，这导致了新的物理效果，其中不同层的属性结合在一起可以实现新的功能。在这些新的效应中，电荷和电子的磁性之间的相互作用是在称为自旋电子学的领域中研究的，自旋电子学是我们当前磁数据存储技术的基础。这个博士生项目有以下目标：-研究其他2D材料(六角形氮化硼)之间封装的石墨烯中的自旋输运，以探索石墨烯中自旋弛豫的来源。-探索增强石墨烯中自旋输运的不同方法。学生将采取以下方法：-开发和改进用于测量纳米设备中自旋输运的实验装置。-探索增强自旋电流的电子控制的不同方法，学生将研究石墨烯在自旋电子学中的电传输特性，将石墨烯与磁性材料和其他新型2D材料相结合，并演示未来自旋电子技术的原理。这项工作将在磁性、电子学和纳米技术领域的交叉点进行。

Two-dimensional (2D) materials like graphene, a single-layer of carbon atoms, exhibit remarkable electronic and thermal properties that make them promising for future electronic devices. Recently, interest in these materials has increased even more due to the possibility of stacking single layers of these materials in a sandwich structure, which leads to novel physical effects where the properties of the different layers combine to enable new functionality. Among these novel effects is the interplay between the charge and the magnetism of electrons, which is studied in a field called spintronics that underpins our current magnetic data storage technologies.This PhD student project has the following objectives:- Investigate spin transport in graphene encapsulated between other 2D materials (hexagonal boron nitride) in order to probe the sources of spin relaxation in graphene.- Explore different methods of boosting the electrical control of spin transport in graphene.The student will take the following approaches:- Develop and improve an experimental set up used to measure spin transport in nanodevices.- Explore different methods of boosting electrical control of spin currents, including building complex sandwiches made of 2D materials.The student will investigate electrical transport properties in graphene for spintronics, using graphene in combination with magnetic materials and other novel 2D materials, and demonstrate principles of future spintronic technologies. This effort will take place at the intersection of the fields of magnetism, electronics, and nanotechnology.
