Prof. Joonhak Oh’s research project aims to develop channels for high-performance organic redox transistors channel and solid electrolyte materials and develop a new organic artificial synapse with maximum driving performance through process optimization for the first time in the world.

As the redox transistor, accompanied by the redox reaction of the gate electrode, can control the energy barrier through gate voltage, it is possible to achieve high retention and low programming voltage simultaneously. The research results lay the foundation for and secure an original material, device, and system technology of the next AI semiconductor that can overcome the limitations of the synapse device and secure future technological competitiveness in the rapidly growing neuromorphic device industry.

In addition, if the sensor-synapse integrated sensory nerve imitation system can imitate sensory nerves, it is expected to positively impact the development of related fields by securing original technology in the field of organic electronic materials as well as the academic impact of the research results.
