Funnano Lab. is interested in enhancing device performances by using novel nanotechnologies. Research is largely focused on self-assembly of polymers, nanoparticles, and nanowires for the fabrication of 2D & 3D sub-10 nm nanoarchitectures. Our nanofabrication technology aims for levels of precision, reliability, and reproducibility suitable for large-scale manufacturing of devices. Devices and systems designed based on our sub-10 nm nanoarchitectures can be potentially applied to energy storage & conversion, optoelectronics, and sensors. Funnano Lab provides a home for creative students and postdocs in pursuit of careers in nanotechnology.

Please feel free to contact Professor Yeon Sik Jung for more information on available positions.
