Semiconductor Nanomaterials for Electrons, Light, and Energy

(Research Description PDF)

The Kim group conducts research on semiconducting nanomaterials and meta-optical systems to advance next-generation technologies in energy conversion, light manipulation in solids, and quantum information processing. We combine precise chemical synthesis, innovative doping strategies, and cutting-edge optical design to create materials and structures with exceptional control over their electronic, optical, and magnetic properties.

New Materials Discovery
We design and grow novel nanomaterials using advanced chemical vapor deposition (CVD) and wet-chemical synthesis, achieving precise control over lattice structure, morphology, and composition. By tailoring dimensionality and crystal architecture, we uncover new quantum and photonic behaviors and establish clear structure–property relationships to enable high-performance device integration.

Unconventional Doping
We develop non-traditional, non-equilibrium doping methods that go beyond conventional semiconductor design. By engineering charge-carrier behavior and light–matter interactions at the nanoscale, we open pathways to transformative applications in optoelectronics, spintronics, and spin-photonics.

Optical Metamaterials
We investigate meta-photonic phenomena in periodic nanostructures, focusing on 1D dielectric “metawires” and nanowire superlattices capable of guiding, confining, and manipulating light at subwavelength scales. Leveraging finite-element modeling, analytical theory, and precision spectroscopy, we design optical bound states in the continuum and high-Q resonances, enabling unprecedented spatial and spectral control for devices such as tunable metasurfaces, solar cells, and quantum photonic circuits.
