On the 6th, Hanyang University announced that Professor Jeong Jae-gyeong (Department of Electric Engineering) developed a ‘stretchable transistor’ technology that can be stretched out and easily change the size.
Flexible OLED that is used for foldable cell phones, which became famous as ‘foldable smartphones,’ such as the Samsung Galaxy Fold and Huawei Mate X, is expected to evolve ultimately into a stretchable display after developing as foldable and rollable displays. Following such flows, the technology that Professor Jeong’s team developed is foreseen to be largely meaningful in the display field in the future.
Commonly, the flexible display uses polyimide as a breadboard so that it can be curved or rolled. However, polyimide has a drawback that it cannot be stretched since it is a hard material.
To overcome the limitation, Professor Jeong’s team made a high-performance oxide transistor over polyimide film and used polyethylene that can be stretched like a rubber band as a breadboard, so that it can be stretched threefold than before and can keep its high electric performances.
Also, they planned a structure with a higher duration by replacing the previous silica gate insulator with a hybrid polymer of zirconium, organic matter, and a crosslinker.
Professor Jeong said, “The hybrid material and semiconductor processing concept can later be applied to rubber breadboard that can be stretched as one wants in the future. Through this, they might be used not only for the display industry but also for various industries such as tablets, clothing, and human skin.”
This research is done with the support of Samsung Electronics Research Funding & Incubation Center for Future Technology’s Next Generation Material / Element Project and the Ministry of Trade, Industry, and Energy’s Element Part Industry Future Growth Basis Project. The research result is published in a world-renowned paper, 「Advanced Functional Materials (IF = 15.6)」 in January. Kim Jeong-o (Department of Information Display Engineering), taking the Ph. D. course joined as the lead author and Professor Hong Yong-taek of Seoul National University joined as a co-author.
