The research team led by Prof. Kim Choong-ik at Chemical and Biomolecular Department developed a new material that is operated stably under high radiation environments, and its research thesis was published in the online edition of Advanced Functional Materials on October 9, a world-renowned material engineering journal (corresponding author: Kim Choong-ik, primary authors: Park Byeong Gyu and Ho Dong Il, doctoral students).

 

The universe, nuclear power plants, and aircrafts are environments in which people can be exposed to high radiation. Under these circumstances, electronic devices easily fail because of high-energy radiation, leading to huge economic loss.

 

Prof. Kim Choong-ik’s research team focused on oxide semiconductor materials to develop a material that is highly resistant to radiation. The team combined various elements of the oxide semiconductor that has high stability and excellent workflow conditions to develop a semiconductor material that is operated stably even if exposed to protons, which comprises most radiation in the universe, for a long time. Through this, the team implemented a semiconductor device.

 

Professor Kim Choong-ik said, “The new oxide semiconductor is proven not to change its properties even after exposed to the same amount of radiation that a satellite receives after a few centuries in space,” and added, “the semiconductor device is a fundamental device that is used under various environments. It is at the center of the existing industries of ultra-thin film liquid crystal display (TFT-LCD) and the next generation organic light emitting diodes (OLED).” He also said, “It is expected that this new oxide semiconductor material will be applied not only to satellites and space stations, but also to nuclear power plants and the aerospace and medical industries.”

 

This research was sponsored by the project for supporting junior-level researchers and the space core technology development project of the Korea Research Foundation.
