Welcome to SB Research Group!
XNL@SKKU spans two fields of study: 1) Molecular Semiconductors and 2) Optoelectronic Devices. In specific, our aims are to explore the grounds-breaking Molecule-level Design of Ideal Electronic Materials and Architectural Design of De Novo Photonic, Energy & Electronic Devices. To this end, our research is based on nanophysical and photophysical engineering, i.e. the Excitonic Engineering, of emerging optoelectronic molecular systems, comprising a broad range of optoelectronic/ photonic/ energy materials such as organic, polymeric, and organic-inorganic hybrid and low-dimensional semiconductors. Utilizing the chemical versatility of those materials, our primary focus has been the ground state engineering of their nano/micro-structures and the excited state engineering of their ultrafast dynamics. Ultimately, the goal is to overcome the predominant non-ideality of the materials and reach toward their theoretical limits. By doing so, we can realize a highly functioning material platform that can generate predictable, transferrable, reliable, and homogeneous properties. We believe it will have a great impact on future electronics such as solar cells, light emitting diodes, photosensors, optical switching and optoelectronic computing.
