The NGON lab dedicates to bringing technological breakthroughs to overcome the current limitations and challenges of optoelectronic semiconducting nanomaterials and devices to realize the next-generation hyper-realistic displays. Especially, we are interested in luminescent high-color purity nanomaterials, including metal halide perovskites (e.g., cesium lead halides, etc.), colloidal semiconductor nanocrystals (e.g., II-VI quantum dots (CdSe, ZnSe, etc.), III-V quantum dots (InP, InGaP, InAs, InSb, etc.)), and their light-emitting diode applications.
We chemically tailor the composition, structure, and surface ligands of the nanomaterials based on novel synthetic routes and surface chemistry to improve their optical/electrical properties and stability. Also, we seek to in-depth understand the fundamental aspects of nanomaterials and devices including structure/property relationships and device mechanisms.
On the other hand, we don't just focus on existing research fields. We aim at pioneering new fields of study by discovering new classes of optoelectronic semiconducting nanomaterials and devices, which are unprecedented. By using a totally different synthetic approach, for example, molten salt-based colloidal synthesis, we develop new nanomaterials which can exhibit outstanding optical/electrical properties for applications to next-generation optoelectronics and displays, DUV/EUV lithography, image sensors, quantum computing, energy, smart healthcare, etc.
