Research Topics

The ability to control the structure and morphology of the surface and interface of thin films at a nanometer length scale is quite crucial for the development of the highly-efficient heterolayer-based electrochemical devices such as solar cells, supercapacitors and secondary batteries.
My research interest ranges from the fundamental understanding on the formation of surface/interface nanostructures of the thin films and their application to the fabrication of efficient (opto)electronic devices.

■ Control of deposition and morphology of organic inorganic thin films at a nanometre length scale

■ Study of growth dynamics and surface nanostructuring of the thin films

■ Development of efficient electrochemical devices, especially supercapacitors and solar cells, using the surface/interface nanostructures.
