Research

Our research is strongly related to the advanced material properties (structural, optic, electronic, magnetic) and its nanostructures for novel functional devices application, such as sensors, memory, spintronics, photonics and optoelectronics. The advanced properties of this material are also useful for improving battery performance, solar cell efficiency, developing a new generation of thermoelectric devices and so on.
