Research Field

1. Multiferroic Materials and Devices

Multiferroic materials, with coexistence of at least two orders (ferroelectric, ferromagnetic, or ferroelastic) have drawn ever increasing interest, motivated by potential applications in information storage, spintronics, and multiple-state memories. In multiferroic materials, the coupling interaction between the different order parameters could produce new effects, such as magnetoelectric effect.

Our group is one of the pioneers in multiferroic material field. Our work covered the theoretical simulation and calculations of the multiferroic composites, the fabrication and characterization of the single-phase multiferroics, the growth mechanism and properties of the heterostructures, and the fabrication and applications of the bulk magnetoelectric composites. We have published dozens of articles in academic journals, such as PRL, APL, PRB, and held several Chinese patents.

2. Organic-inorganic Functional Composites

By embedding the inorganic (nano) particles into the polymer matrix, as well as controlling the particle distribution and particle-polymer interface, the electric, magnetic and optical properties of polymer can be greatly enhanced. The related researches in our group are mainly focused on two aspects: (1) Using the percolative effect induced by conductive powders in the polymer matrix to get the novel high-performance polymer-based composites; (2) By designing the microstrures to acquire the polymer-based composites with both of capacitive and inductive properties

3. Solid State Electrolytes and Electrodes for Lithium Batteries

Lithium ion solid state electrolytes have large potential applications in the portable sets and power system. Our group has been engaging in the polymer-based nano composite solid state electrolytes and inorganic solid state electrolyte. With the idea of enhancing the conductivity of lithium ions, we mainly focus on the optimization of materials and the interface effects in multiphase composite

4. Transition Metal Oxides

Transition metal oxides have abundant functions, and our group's researches are mainly focused on the following two aspects: (1) Thermoelectric (TE) materials: enhance ZT values of cobalt-based TE materials by controlling the microstructures of materials (e.g., metal doping and novel sintering processes of ceramics ); (2) Giant dielectric materials: grain boundary layer structures are formed in NiO-based ceramics via doping, and thus a new type of giant dielectric materials that are non-ferroelectric, non-perovskite and lead-free, can be obtained.

5. Calculations of Microstructure-Property Linkages
