Our approach to the problem:
Structure optimization based on three-dimensional electromagnetic numerical simulations
State-of-the-art chemical syntheses with a sub-5 nm spatial resolution in all three-dimensions
Fundamental studies in photoelectrochemistry (water-splitting photocathodes), plasmonic photocatalysis (gas phase photomethanation) and Surface-Enhanced Raman spectroscopy (SERS)
Our three-dimensional electrochemical axial lithography (3DEAL) technique can be used to pattern macroscopic arrays of single-crystalline Si micro- and nanowires with feature dimensions down to 5 nm.
We are currently using 3DEAL to design substrates for 3D surface-enhanced Raman spectroscopy (SERS) and water-splitting photoelectrodes.
