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

像石墨烯这样的二维（2D）材料，单层碳原子，表现出非凡的电子和热性能，使它们在未来的电子设备中具有前景。最近，人们对这些材料的兴趣增加了，因为这些材料可以在三明治结构中堆叠单层，从而产生新的物理效应，其中不同层的特性结合在一起，从而实现新的功能。在这些新效应中，电荷和电子磁性之间的相互作用是在一个叫做自旋电子学的领域进行研究的，该领域是我们目前磁性数据存储技术的基础。这个博士生项目有以下目标：-研究包裹在其他二维材料（六方氮化硼）之间的石墨烯中的自旋输运，以探测石墨烯中的自旋弛豫的来源。-探索增强石墨烯中自旋输运的电气控制的不同方法。学生将采取以下方法：-开发和改进用于测量纳米器件中自旋输运的实验装置。-探索增强自旋电流电气控制的不同方法，包括用2D材料制作复杂的三明治。该学生将研究自旋电子学中石墨烯的电输运特性，将石墨烯与磁性材料和其他新型二维材料结合使用，并展示未来自旋电子学技术的原理。这一努力将发生在磁学、电子学和纳米技术领域的交叉领域。

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.
