Research Projects

 

1.       Multiferroics and multifunction

          多铁性和多功能

Multiferroics are materials have at least two ferroic properties, e.g., ferroelectricity and ferromagnetism.

 

Studying this group of materials will help us understand clearly the interaction between electric field and magnetic field inside materials. In another hand, because it offers a possible way to control magnetism with an electric field (or change polarization via a magnetic field), multiferroic thin film can lead new type memory, sensors and other devices.

 


Figures above showed the relationship between electric field, magnetic field and stress(left) and the multiferroic materials families(right).

 

2.       Smart  and bio-inspired devices

           智能和仿生器件

Smart materials can sense and respond to the environment around them in a predictable and useful manner. Some types of smart materials include piezoelectric, shape memory, thermochromic, photochromic, magnetorheological and so on.

 

Learning from nature means taking ideas from nature and developing novel functional materials based on these concepts. For example, lotus leaves have self-cleaning effect because of the mastoids on their surface.

 

Studying these group of materials will help us open up new possibilities in many areas and create useful devices.
