Lee research group emphasizes the integration of materials synthesis, interfacial properties, and applications. Group members are expected to develop skills and knowledge of fundamental understanding of the problems, scientific approaches, and applications of final products.
1. Surface modification (表面處理)
The surface modification technique employed in our laboratory focuses on the formation of self-assembled monolayers (SAM) on various substrates. This organic thin film derived from the adsorption of molecules on solid substrates has been extensively studied over the past two decades. These spontaneously adsorbed thin molecular films have thickness ranging from few Å to 2 nm. Due to the functional group tethered at the end of the molecule, the surface properties can be greatly changed. This unique property provides potential applications in many areas, such as biomaterials fabrication, lithographic patterning, and thin-film lubrication. In recent years, we have developed a standard procedure to generate high quality SAMs on oxide and silicon substrates. These modified substrates will be used for further inorganic thin film fabrications and colloidal particle self-assembly studies.
2. Material synthesis using wet chemistry process (濕式化學法合成材料)
In our laboratory, materials synthesis is generally divided into two directions: (1) particle/nanoparticle synthesis; (2) thin film deposition. Wet chemistry process is used for particle and thin film fabrication. Currently, we focus on the generation of metal sulfide compound semiconductor, including ZnS, AgInS2, AgIn5S8, and ZnS-AgInS2 solid solutions. For the particle system, final products depend strongly on the details of the solution chemistry. We have investigated the effects of chelating agent, pH value, and concentrations of the precursor solutions. The next step is to develop a robust protocol to precisely control the morphology, composition, and crystal structures of the particles. For the thin film system, these metal sulfides are deposited on the modified substrates. Self-assembled monolayers (SAMs) with various functional groups are tethered onto the substrate surface in order to manipulate the surface properties. As a result, different compositions and phases of the sulfide thin films can be easily fabricated.
3. Energy applications (能源應用)
Two types of energy applications are under investigation: (1) solar hydrogen production and (2) energy storage systems, typically various battery systems. For the solar hydrogen production, we study the solar-to-fuel conversion using photocatalytic and photoelectrochemical (PEC) system. The metal sulfide materials mentioned above, are used as the active materials for hydrogen production from water splitting. The fundamental materials properties, as well as the charge transfer inside the system are investigated. For the battery systems, we will explore the utilization of metal sulfide materials as the negative terminal.
