主要研究方向如下:

1. 铁磁二维材料自旋调控研究

    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. 铁磁、铁电二维材料CVD生长

     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.

3. 智能超表面

    Plasmonic arrays have attracted great interest due to their fantastic properties in controlling electromagnetic waves in the applications of light engineering, imaging, and holography. Metasurfaces have been used to control the wavefronts of circularly and linearly polarized light in the visible and near-infrared regions, in which the aligned nanostructures, such as metallic nanorods, V-shapes, and silicon (Si) cut-wire resonators generate abrupt phase changes along the surface. However, it is still a major challenge to realize large-scale active plasmonic arrays operation in the visible optical frequency.
