Research Interests

Theoretical prediction on the properties of TADF based OLED materials; First principle studies on surface doping of low-dimensional materials; Nanoscale heat transfer and thermoelectric materials; Size and shape effect of nanoscale thermodyamic properties.

Research Experience and Accomplishments

Based on the recent research activities, he published more than 30 research articles and 1 book, including the journals Phys. Rev. LettSmallPhys. Rev. B. The research results are presented in more than 10 international conferences, including 1 invited talk. The developed models have been widely used to explain the experimental results. Part of them are follow-up studied by other research groups and are written in text books. Because of the high research performance, he earned many awards, such as the Alexander von Humboldt fellowship, the excellent master thesis of Hunan Province, the first prize of excellent Master graduates in research of Central South University etc. The main achievements include : 1, investigated the heat transfer transition from near-field radiation to heat conduction and the corresponding mechanisms. 2, systematically studied the effects of defect on heat conductions in nanomaterials. 3, developed several thermodynamic models to describe the properties in nanomaterials, such as size and shape dependent phase transition temperature, melting entropy and alloying abilities etc.
