Currently, my research focuses on the growth of nitride semiconductor crystals using the molecular beam epitaxy (MBE) method. My primary aim is to develop advanced gallium nitride (GaN) and related wide-bandgap materials with superior crystalline quality and controlled doping profiles. This involves meticulous control over epitaxy processes to achieve low defect densities and optimize heterostructure interfaces. The ultimate goal is to enable the fabrication of low-loss and high-efficiency power conversion devices, including next-generation power electronics (e.g., rectifiers, inverters) and high-frequency communication components. By enhancing material properties and device performance, this work directly contributes to significantly reducing energy consumption in power grids, electric vehicles, and data centers, thereby playing a crucial role in achieving a sustainable and carbon-neutral society.
After completing my Ph.D., I pivoted my research focus towards renewable energy generation, driven by the critical need to mitigate climate change. My work initially explored solar cells and microbial fuel cells. In solar cell research, I championed the use of low-cost, abundant materials for dye-sensitized solar cell electrodes, offering a sustainable alternative to expensive platinum. I also engineered mesoporous TiO2 nanoparticles to enhance photoanode performance and developed quasi-solid electrolytes to extend device lifetime. Concurrently, my microbial fuel cell studies delved into the fundamental properties of electron-producing bacteria, exploring their applications in renewable energy, biosensors, and smart organic agriculture. This included developing cost-effective, high-performance electrode materials and pioneering practical designs for these fuel cells.
During my master's, I conducted research on creating compact and printed ultra-wideband antennas with the possibility of self-rejecting electromagnetic interference caused by some narrow bands allocated to other communication systems. In addition, my Ph.D. research focused on developing novel techniques for generating ultrashort optical pulses using fiber lasers for applications in broadband optical communication, high-precision material micromachining, and medical imaging. To realize this goal, I have proposed new techniques to generate picosecond and femtosecond optical pulses using fiber ring laser systems.
