The Liu Group aims to advance the next-generation optoelectronic materials for applications in energy, sensing, and information technologies. We focus on developing chiral materials for geometric deep optical sensing, colloidal nanocrystals for infrared light detection and emission, as well as multiferroic semiconductors for advanced electronics and spintronics. Using cutting-edge spectroscopies, we explore the fundamental physical properties of materials, and leverage these insights to enable novel device concepts and push device performance to the limit.
