Professor Hyo Jae Yoon (Department of Chemistry) and his team have succeeded in creating a new molecular diode that shows a reversal of rectification polarity depending on the magnitude of the voltage applied. The research was published in the Journal of the American Chemical Society with the support of the Korean Research Foundation.

Semiconductors are an indispensable global commodity for the fourth industrial revolution and have reached the stage where it is difficult to improve integration with traditional lithography techniques. Fortunately, Professor Yoon’s team has brought this technology to the next level through repeated substation method where the rectification characteristics at previously unreachable voltages where studied. The newly developed molecular diode can reach the voltages which had created challenges during research for technological advancements in semiconductors. This achievement, is expected to facilitate further research related to improvements in semiconductors.
