RESEARCH AREA

We pursue the development and application of atomic layer deposition (ALD) techniques, such as vapor-phase infiltration (VPI)/ sequential infiltration synthesis (SIS), towards the materials innovation in micro/nanoelectronics, solar energy conversion, catalysis, and membranes.

Combining the polymer nanopatterning based on conventional lithography and block copolymer self-assembly, we generate unique organic-inorganic hybrids and inorganic nanostructures with various functional applications

Our experimental strength in ALD techniques is combined with our longstanding expertise in advanced materials characterization and semiconductor device physics & fabrication.
