Introduction to award winners
High-precision assembly of DNA-coated colloidal transistors
The directed self-assembly process was proposed as the next-generation semiconductor manufacturing process, and a lot of research has been conducted, but as research for assembling nano materials at a certain location has such low precision, a lot of improvement must be made. Prof. Gira Yi’s research project aims to manufacture distributable transistor devices for overcoming this limit and use DNA to assemble them at a certain location.
Research on the manufacturing of colloidal transistors and DNA-coated assembly can improve the existing top-down device manufacturing process, which was difficult as the 2D plane was utilized. Plus, as they can be applied to the assembly of DNA-coated nano materials, they can be used for a variety of purposes, e.g. the nano optical device, solar cell, smart window and quantum computer manufacturing process.
Study on the synthesis of multi-heterocycles using the nickel catalyst
Prof. Eunjin Cho‘s research project aims to implement a nickel catalyst system that is not sensitive and reacts in mild conditions to then use it to synthesize various functional heteropolycycles.
Over the years various methods of synthesizing heterocycles have been developed, but the synthesis of heterocycles with several substituents took a lot of time and cost. It seems that this study will make it possible to synthesize heteropolycyclic compound derivatives with various substituents, which were not easy to synthesize, and build a new library. The completed synthesis roadmap will make it possible to explore structure-activity relationship in new drug development and research on biomedical sciences and materials. This study is expected to contribute to the development of related fields.
2D and 3D printing of 3D colloidal arrays for customizable structural-color patterns
Prof. Shinhyun Kim’s research project aims to recognize the limits of the standardized pattern production technology with a single structural color in the age of technological sensibility and realize a structural-color for 2D/3D printing and colloidal self-array through the direct writing of the photopolymerizable colloid ink that can overcome this limit.
It will be possible to lead the high-sensitivity optical materials technology by implementing various colors and color sense, which cannot be implemented by chemical pigments, by imitating the structural colors of nature and commercializing structural pigments with high thermal stability and low toxicity, and patternize aesthetic structural-colors without pigments in various areas of our daily life, e.g. various clothes and accessories, contact lenses and smartphones.
Organic redox transistors and their applications in artificial synaptic transistors
Prof. Joonhak Oh’s research project aims to develop channels for the high-performance organic redox transistors channel and solid electrolyte materials and develop a new organic artificial synapse with maximum driving performance through process optimization for the first time in the world.
As the redox transistor accompanied by the redox reaction of the gate electrode can control the energy barrier through gate voltage, it is possible to achieve high retention and low programming voltage at the same time. The research results are expected to lay down the foundation for and secure an original material, device and system technology of the next AI semiconductor that can overcome the limit of the synapse device, and secure future technological competitiveness in the rapidly growing neuromorphic device industry.
