FunNano Group is interested in enhancing device performances by using novel and practical nanotechnologies. We are studying new self-assembly materials and techniques forming sub-10 nm nanostructures based on polymers and nanoparticles. Our novel self-assembling systems aim for much superior precision, reliability, and reproducibility that would be adequate for large-scale manufacturing of nanoscale devices. Applications include sub-10 nm lithography, energy storage/capture devices, and sensors. Our group wants to be a joyful playground for creative students and postdocs pursuing careers in nano-science and nano-engineering. Please feel free to contact the group leader (Prof. Yeon Sik Jung) at ysjung@kaist.ac.kr to get more information or to make an appointment.
