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.

二维（2D）材料，如石墨烯，单层碳原子，表现出显着的电子和热性能，使它们有希望成为未来的电子器件。最近，由于在夹层结构中堆叠这些材料的单层的可能性，对这些材料的兴趣已经增加得更多，这导致了新的物理效应，其中不同层的性质结合联合收割机以实现新的功能。在这些新的效应中，电子的电荷和磁性之间的相互作用是在自旋电子学领域中研究的，该领域是我们当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。-探索不同的方法来提高石墨烯中自旋输运的电控制。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。-探索不同的方法来提高自旋电流的电控制，包括构建由2D材料制成的复杂三明治。学生将研究用于自旋电子学的石墨烯的电输运特性，将石墨烯与磁性材料和其他新型2D材料结合使用，并展示未来自旋电子技术的原理。这项工作将在磁学、电子学和纳米技术领域的交叉点上进行。
