The Kim group’s research has been centered on developing new photonic and electronic devices at micro and nanoscales involving various functional materials such as rare-earth doped oxides, wide bandgap semiconductors, ferroelectric films, and plasmonic nanostructured materials.

Their research in the nanotechnology area investigates multiscale vertical integration of nanostructures into hierarchical systems. Single-domain ordered nanochannel arrays with controlled symmetry have been developed on macroscale area of wafer surface using a directed self-organization method, and have been investigated as an interaction medium in optical, electrical, chemical, and biological domains. Surface-plasmon phenomena occurring in nano-optic structures are of particular interest, since many novel properties can be derived from those and can be incorporated into an on-chip configuration for interaction with other functional materials.

The Kim group investigates plasmonics as an enabling technology for implementing nanosystems-on-a-chip that offer multifunctionality across the heterogeneous domains.
