Researchers at KIST and Gwangju Institute of Science and Technology (GIST), led by Dr. Yusin Pak at the Sensor System Research Center (KIST) and Professor Gun Young Jung at the School of Materials Science and Engineering (GIST), have developed ultra-high-speed, high-efficiency optoelectronic logic gates (OELGs) by using organic-inorganic perovskite photodiodes.
Demand is increasing for computers that can quickly calculate and process large amounts of information, as artificial intelligence, self-driving cars, drones, and metaverse technologies are drawing attention as core industries of the future. However, electronic semiconductor logic gates, which serve as the brains of computers, have limited capacity in high-speed data calculation and processing, and have disadvantages in that they consume a lot of energy and generate considerable heat.
