My main goal is to set up a high-efficiency in-situ CL detection system in an electron microscope to fulfill characterization of CL spectra from nanoscale regions of materials.

Research

I got my PhD degree in Condensed Matter Physics from Beijing University of Technology in 2008. From 2008-2010, I worked as research fellow in University of Science and Technology Beijing. I joined CRANN and Trinity College in 2010.

From 2004-2008, my research focused on microstructure of defects in Al-N-Rh alloys by HRTEM and other related methods. From 2008-2010, my research concerned with the Microstructure and phase transformation in structure complex phases in Ni- and Co-based alloys using SEM and TEM.

Dye Sensitized Solar Cells (DSSCs)

During 2010-2012, my research focused on microstructures of the dye sensitized solar cells (DSSCs) interfaces and the relationships between type and distribution of impurities by TEM and SEM. My main goal was to disclose the structural and compositional features responsible for the energy loss of the DSSCs, understand the loss mechanisms, and thus facilitate the development of new processes to improve the performance of the cells.

Cathodoluminescence of Semiconductors

Now my research is focused on in-situ CL(cathodo-luminescence) of semiconductors. The main goal is to set up a high-efficiency in-situ CL system in an electron microscope to fulfill characterization of CL spectra from nanoscale regions from materials.
