Welcome to Our Research Group!
Welcome to Our Research Group!
In XNL@SKKU, we achieve breakthroughs in emerging photonic, energy & electronic materials, based on nanophysical and photophysical engineering of their excited states, i.e. the Excitonic Engineering. In specific, we explore chemical versatility of De Novo molecular systems such as organic, polymeric, organic-inorganic hybrid and low-dimensional materials, in order to engineer their nano/micro-structures and non-equilibrium quantum dynamics at functional interfaces. 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. If you are interested in advancing science and technology of molecular optoelectronics, Join US in the adventure!
