Welcome to Nanoelectronic and Optical Devices Laboratory (NEOL)!

In NEOL, we are developing novel nanoscale electron devices, high-efficiency optical devices with higher scalability, and the integrated circuits for ultra-low-power/high-speed applications and for the next-generation VLSI systems. Also, bio-motivated and bio-interacting electronics are under research for quenching the issues in electron devices/ integrated circuits and for deeper influences on our daily lives. Pursuing the goals, we are making efforts to deliver good news to the technical society and many people.

Anyone who is interested in working in our research group, as either graduate or undergraduate research member, is welcomed to contact Prof. Seongjae Cho through felixcho@gachon.ac.kr or leave a message in the Contact Information tab.
