New Materials Discovery
Novel nanomaterials with tunable electronic, optical, and magnetic properties are vital to emerging applications in energy conversion, quantum information processing, and photonic technologies. Our research focuses on discovering new semiconducting nanomaterials and quantum building blocks through chemical vapor deposition (CVD) and wet-chemical synthesis, with precise control over lattice structure and dimensionality, crystal morphology, and chemical composition. Establishing clear correlations between crystal structure and electronic, optical, and magnetic behavior is essential to enabling their integration into high-performance device architectures.

Unconventional Doping
Doping in crystalline solids offers a powerful means to engineer a material’s fundamental properties. Our CVD-based strategies enable new ways to realize non-traditional and non-equilibrium doping configurations and to manipulate the behaviors of charge carriers in semiconducting solids. Through this control, we aim to enhance light–matter interactions for advanced optoelectronic, spintronic, and spin-photonic applications.

Optical Metamaterials
The Kim group investigates the meta-photonic behavior of nanoscale metamaterials, with an emphasis on periodically repeated structures that manipulate light at subwavelength scales. Our research focuses on one-dimensional (1D) dielectric optical metawires capable of guiding, confining, orienting, and absorbing light with high precision, enabling device concepts with unprecedented spatial and spectral control.
