ATFLab conducts research in electronic materials, processing and devices, which include transparent electrodes for optoelectronics, low-resistivitiy interconnects for semiconductor devices, multi-functional transparent heaters, protective encapsulation layers, resistive-switching devices, electrochromic devices, among others. Our primary goal is to address conventional challenges by pioneering innovative thin film technologies. We are currently recruiting graduate students and postdoctoral researchers for the university-designated Research Professor positions. If you are interested, please contact dhchoi802@gachon.ac.kr. Please avoid sending generic, "copy-and-paste" emails. I carefully review applicants who demonstrate genuine enthuiasm for research that aligns with our interests.
ATFLab은 혁신적인 재료/공정/소자 연구를 통해 광반도체용 투명전극, 실리콘 반도체소자용 인터커넥션, 다기능 투명면상발열체, 투명봉지막, 저항변화 소자, 전기변색 소자등에 대한 연구를 수행하고 있습니다. 함께 나아갈 학부 연구원, 대학원생, 박사후 연구원을 모집합니다. 관심 있는 사람은 dhchoi802@gachon.ac.kr로 연락주기 바랍니다.
