Since the optoelectronic technologies cover a wide range of human life including optical data processing (computing), lighting, renewable energy sources, environmental- and bio-technologies, it is essential to explore new science and functionalities in novel optoelectronic materials based on light-matter interactions such as quantum, nanophotonic, and plasmonic/meta-materials. The research in Nanoscale Optoelectronic Materials Laboratory focuses on finding novel optoelectronic properties, designing materials, and developing advanced optoelectronic devices.

The mission of Light and Matter Theory Laboratory (LMTL) is to explore the dynamical nature of correlated electron systems driven by the matter-photon interaction. Especially, the exploration of dynamical linking of competing degrees of freedom depending on various time scales is a main issue of LMTL. Detailed research options include the photoinduced phenomena, optical manipulation, time-resolved spectroscopy, attosecond photoemission, and etc, which should be steps toward the next-generation light-wave solid-state electronics.

The Computational Materials Design (CMD) Group uses atomistic simulations to understand emergent properties of real materials at the nanoscale. Our goal is to better design new functional materials from developing fundamental understanding of materials. Our research combines aspects of materials physics, chemistry, and computer science. The primary tool is density-function theory (DFT), which is used to solve quantum mechanics of electrons in materials. Research areas of interest include, but are not limited to: (i) design of materials for energy conversion, storage and transport, (ii) development of bio-inspired, neural-network many-body potentials for multi-scale atomistic simulations, and (iii) computational study of simple emergent behaviors of “complex” systems.
