中文摘要
低维量子体系中本征磁性与非平庸拓扑能带结构间的相互作用可有效调控电子自旋,产生丰富的量子物理效应,为后摩尔时代高性能、低功耗自旋电子器件的开发提供了新的机遇。然而,高质量磁性拓扑材料的生长通常难度较高,限制了很多新奇量子现象的观测与器件应用。利用二维磁性材料与拓扑材料构造异质结有望解决这一问题:通过界面近邻效应,可将长程磁序与拓扑表面态直接进行耦合。申请人长期从事低维范德华异质结的制备与表征,曾对CrI3、CrCl3、WTe2等二维磁性材料与拓扑材料的物理性质进行系统研究。本项目拟制备一系列低维磁性拓扑异质结构,利用低温电磁输运、磁光克尔效应、扫描光电流测量等多种表征技术,探索其中的拓扑边缘态、界面磁性等新奇量子效应,并利用磁场、电场、光场对相应的物理现象进行人工调控,在此基础上设计和构筑一系列新型自旋电子原型器件,为其未来在微电子工业的实际应用提供原理性支持。
英文摘要
The interaction between the intrinsic magnetism and the non-trivial topological band structure in the low dimensional quantum system can effectively control the electron spin, generating multiple quantum mechanical effects, and providing new opportunities to the development of the spintronic devices with high efficiency and low power consumption in the Post-Moore Era. However, the growth of the magnetic topological materials with high quality is difficult, limiting the observation of many novel quantum mechanical phenomena and the application of devices. To construct a heterostructure using two dimensional magnetic material and topological material may solve the problem: The long-range magnetic order can directly couple to the topological surface state due to the proximity effect at the interface. The applicant is experienced in the fabrication and characterization of low dimensional van der Waals heterosturctures and has systematically studied two dimensional magnetic and topological materials, including CrI3, CrCl3, WTe2, etc. In this project, we propose to fabricate various low dimensional magnetic topological heterostructures. We will explore the topological edge state, the interface magnetism and other novel quantum mechanical effects by using the characterization technique such as the low temperature electromagnetic transport, the magnetic Kerr effect, the scanning photocurrent microscopy, and tune the corresponding phenomena with multi-physical field. According to this, we will design and construct a series of novel spintronic prototype devices, providing the support for the future application in microelectronics industry.
