Goal

The goal of our research group is development of new classes of nanomaterials to provide solutions for recent energy & environmental issues.

Advanced metal oxides are attractive semiconducting materials due to their outstanding electric & chemical properties, and high stability. We are aiming to develop next generation metal oxides possessing improved nanoscale architectures, interface, and characteristics to realize advanced optoelectronics.

Colloidal quantum dot is very small (2~10 nm) sized semiconducting nanoparticles showing quantum confinement effect. Colloidal quantum dots (CQD) are promising semiconductors for optoelectronic devices, including light-emitting diodes, photodetectors, and photovoltaics because of their size dependent bandgap tunability, solution processability, and good air stability. In particular, the size-tunable bandgap of CQDs provides an opportunity to harvesting the near infrared (IR) region of solar spectrum, representing a promising strategy to supplement a performance of wide bandgap photovoltaics. Our research interests are development of highly efficient IR CQDs, advanced device architectures, and realize toxic materials free CQDs etc.

Perovskite-quantum dot hybrid nanomaterials are promising platform to exploit outstanding photo physical properties of perovskite and quantum confinement effects. There are two different type in these materials, one is perovskite their urgent issues including synthetic methods, materials processing, stability, and performance etc.
