POSTECH: Yeseul Kim Wins Gold Medal at ‘Nano Korea 2021’

Yeseul Kim, (Academic advisor: Professor Junsuk Rho of Department of Mechanical Engineering and Chemical Engineering) who is in the MS/PhD integrated program of the Department of Mechanical Engineering at POSTECH, won a gold medal at the ‘Nano Korea 2021’ organized by the Ministry of Trade, Industry and Energy and the Ministry of Science and ICT.

Nano Korea 2021 is a symposium to promote nanoscale science and technology, to increase exchanges among researchers in relevant fields, and to materialize the results of research. In this symposium, one grand prize, two gold medals, and three silver medals were selected among general participants.

A Kim’s paper, ‘Spin-valley Locked Edge States in Chiral Photonic Crystal’, has designed that the Spin-valley Locked Photonic Crystal with both quantum spin-hole and valley-hole effects, and proved that one-way photon transport by using multiple degrees of freedom based on the condition of spin and valley. Through this research, Kim was praised for opening up the possibility for highly efficient and powerful signal transmission, and was honored with the gold medal at Nano Korea 2021.

“Thank you for giving me a great chance to present at this honorable academic conference,” Kim said. “I will constantly do research to apply my research in various areas such as optical communication and topology spintronics.”
