Professor Lee Jong-heun is a world-renowned scholar in the field of oxide semiconductor
gas sensors that detects various gases instead vof human olfactory sense.

In the field of oxide semiconductor gas sensor field, it has been difficult to selectively detect a trace gas or specific gases. However, Professor Lee has pioneered a new field that selectively detects various gases with ultra-high sensitivity, ultra-high speed, and high selectivity using regularly self-assembled oxide nanostructures of nano building blocks and p- type oxide semiconductor. In addition, he proposed a semiconductor gas sensor design that is not affected by changes in the humidity in the outside air.

Only Professor Lee was selected as one of “16 Highly Cited Researchers” among Korean scientists in the field of engineering by Thomson Reuters in 2014. Academic information provider Thomson Reuters selected his research of semiconductor gas sensor as Top 1% cited research over the last 10 years.

Having solved the fundamental problems of existing semiconductor-type gas sensors, Professor Lee's fundamental achievements are expected to be applied to various application fields surpassing human olfactory sense such as hazardous and explosive gas detection, air pollution monitoring, real-time disease diagnosis, IoT-connected smart home, sensor network It is expected to be widely used in applications.
