※ Professor Hyun Yong Choi has published a paper on ACS Photonics, an international academic journal, by studying the mechanism of spin alignment, generation, transport, and extinction by light and electric fields inside a three-dimensional phase insulator through ultra fast time resolution photocurrent measurement.

※ The study was led by Professor Choi, Hyun - Yong 's lab, and it is expected to have a great impact on spintronics by measuring the highest record of the charge - to - spin conversion ratio through research.
