Hae-Jeong Lee, Ph.D.

Research Interests

  • Developing new metrology to characterize nano-structures in thin film and membrane using X-ray reflectivity (SXR), small angle x-ray scattering (SAXS), grazing incident small angle x-ray scattering (GI-SAXS) and small angle neutron scattering (SANS)
  • Study on the effects of confinement geometry on crosslinking density of UV nanoimprint resist
  • Developing advanced characterization methods for determining regular and irregular nano- and micro- scale patterns using SXR as a pattern shape metrology
  • Developing novel resist for high resolution e-beam lithography and fabricating reliable nano-patterns using newly developed resist 
  • Structural characterization of porous thin films including porosity, average pore size, pore connectivity, pore size distribution, matrix density, average film density, and water uptake using SXR, SAXS, GI-SAXS, and SANS
  • Characterizing surface and interfacial structures and density depth profiles of thin films
