Research Interests

Our research spans over a broad range of molecular optoelectronics based on emerging optoelectronic/photonic/energy materials including graphene, organic, polymeric, and organic-inorganic hybrid semiconductors. Utilizing the chemical versatility of those materials, our primary focus is 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, it will be possible to realize a highly functioning material platform that can generate predictable, transferrable, reliable, and homogeneous properties. It will have a great impact on future electronics such as solar cells, light emitting diodes, photosensors, optical switching and More-than-Moore optoelectronic computing.
