高频运算与存储、低功耗是后摩尔时代集成电路发展的技术趋势和迫切需求，而当前冯·诺依曼计算构架中存储与计算单元分离，且速率相差5个数量级，导致严重的性能和功耗瓶颈，限制了集成电路系统的发展。本课题组针对冯·诺依曼计算构架存储墙难题，致力于开发自主创新的超分辨多物理场磁光光谱技术，探索时间、空间分辨极限下低维关联体系中的新奇磁光、磁电耦合现象与机制，解决与材料科学、凝聚态物理等领域相关的基础科学问题，研发下一代电控磁技术、磁存储器和存算一体技术。

主要研究方向如下：

1. 电场调控低维铁磁材料自旋机制研究

    Ferromagnetism, refers to a permanent magnetic moment without applying any external magnetic field when the temperature is below a critical value-Curie temperature (Tc). Through the ages, the three-dimensional (3D) ferromagnetic with high Tc can be easily achieved. However, according to the Mermin-Wanger theorem, the finite-range exchange interaction cannot preserve the long-range magnetic orders in 2D system which can be destroyed by the thermal fluctuation at nonzero temperature. Cutting through the limitation of Mermin-Wanger theorem requires strong enough magnetic anisotropy overcoming the thermal fluctuation like the way the 2D Ising model are. Thus, introducing magnetic anisotropywill make the way to long-range magnetic order at finite temperature and 2D ferromagnetism possible. The spin states and spin-wave can be harnessed to carve out a path to realize modulator, spintronic and memory devices.

2. 低维铁磁材料晶圆级生长制备研究

     At this stage, the key questions that are being addressed are that 2D ferromagnetic and ferroelectric materials can be reliably larger-scally synthesized with high quality and higher Tc.  Once, the constraints are overcomed, the potential for technological impact is enormou.
