Soft via fabrication (Nature Electronics)
Electric energy transmission in extreme environments, such as the deep sea, outer space, and under high mechanical strain, presents unique requirements for electrical components. Conventional materials face significant limitations in these challenging conditions, underscoring the urgent need for the development of new materials and processes. I aim to explore innovative methods and technologies that can efficiently harness and transfer energy while addressing the unique challenges posed by these environments. By understanding these factors, I hope to contribute to advancements in energy efficiency and sustainability.
Ion-based energy control
Battery and many other devices use ionic species as the storage for electrical energy. Speed of the ionic species is slower than the electron therefore its usage in the computing and control electronics have been limited. But, its localized concentration and interaction with polymer matrix provides interesting memory and thermoelectrical behavior.
We want to control and uitilize the dynamics of the ionic species in the 3D polymer matrix through modification of the iongel's composition and its fabrication process.

(Advanced Functional Materials)
More and more electronic systems require high electrical power, such as electric vehicles, AI servers, and systems for megastructures. Conventional silicon-based semiconductors have a small bandgap structure, which limits their usage in high-voltage and high-temperature systems. To overcome these issues, wide bandgap semiconductors such as GaN and SiC have been studied. However, there are challenges in fabricating high-quality wide bandgap semiconductors in large areas for mass production.
We aim to develop the fabrication of wide bandgap semiconductors using Liquid Metal (eGaIn) in an ambient environment, leveraging its unique material properties.
