Materials patterning at the liquid-solid interface
National Taiwan University, NTU
Dr. Shern-Long Lee received
his PhD degree from the department of chemistry at NTU in 2009. He worked as a
postdoctoral research associate at NTU 2009-2012 and at K.U. Leuven, Belgium
2012-2015, respectively. He is currently working at NTU as a research assistant
professor. His research interests range from materials chemistry, surface
science, electrochemistry, nanotechnology to microscopic techniques.
The control of
morphology of materials is crucial for their mechanical and device performance.
My research mainly focuses on methodological development for precise
fabrication of highly ordered 2D nanostructures as well as
structural/electrical analysis of materials properties by scanning tunneling
microscopy/spectroscopy (STM/STS). We have developed a
solution-based processing approach for molecular patterning on solid surfaces.
This approach is quite useful for the field of surface materials chemistry. For
example, this approach enables DNA-like polymeric materials to pack together
and constitute a stable 2D thin film allowing high-resolution STM
visualizations. This approach is also able to align functional materials into
well-ordered 3D architectures. Such control can tailor materials properties
(e.g., promoting electron transfer efficiency). Furthermore, this approach
shows significant impacts on the field of molecular crystal engineering.
Moreover, this method can also work as a separation technique because it allows
rapid screening and separation of molecular polymorphs on a surface.
