Department of Electronic and Electrical Engineering Selected for “Semiconductor Track Program”
The Department of Electronic and Electrical Engineering in the Division of Advanced Technology at ELTEC College of Engineering was selected for the “semiconductor track program” as part of the “2022 Collaborative Intra-government Expertise Cultivation Project,” which is jointly organized by the Ministry of Education and the Ministry of Trade, Industry and Energy. The “semiconductor track program” is designed to develop advanced technologies and supply professionals required by industries, aiming to strengthen the national competitiveness of the semiconductor industry. With funding of KRW 900 million for the next three years, Ewha aims to lead the future semiconductor industry by newly-establishing two semiconductor design tracks, the SoC (System-on-Chip) track and the Circuit track, under the Department of Electronic and Electrical Engineering, in addition to producing more than 40 undergraduate students every year through specialized training programs in semiconductor design. To this end, Ewha plans to form a consortium with domestic semiconductor companies, including LX Semicon, SAPEON Korea, Telechips, Semi Five, VisioNexT, etc., and operate training courses that reflect various issues in the industry. Students from their junior year can complete the program by taking more than 21 credits in major foundation courses and major courses including four subjects designated by each track. For practical training, the program courses will utilize Electronic Design Automation (EDA) tools and intellectual properties (IP) that are actually used in the industry and provide special lectures on semiconductor design and others during vacation time to enhance the practical experience of students in the field. Professor Kim Ji-Hoon, the director of the program, remarked, “Since the semiconductor business is a major strategic industry for our country, it is crucial for Korea to extend its competitiveness from a focus on memory chips to various system semiconductors and strengthen competitiveness in ultra-fine processing. We will organize the program to reflect actual industry trends in our department’s outstanding curriculums, so we can provide students with a solid foundation in semiconductor design and various opportunities for practical training. In addition, we will continue to expand the consortium by attracting more companies and establish a council for academic-industry-research institute cooperation so as to respond promptly and effectively to the rapidly-changing semiconductor industry.” The Department of Electronic and Electrical Engineering at Ewha Womans University leads new trends in electronic and electrical engineering by applying AI technology to core research fields, including network and communication systems, semiconductor devices and design, image and signal processing, and semiconductor control, following the advent of the Fourth Industrial Revolution. It is conducting cutting-edge research projects in electronic and electrical engineering based on artificial intelligence by collaborating with renowned companies, government agencies, and universities at home and abroad, thereby garnering recognition for its accomplishments from world-class academic societies and journals. Moreover, particularly in the semiconductor and circuit design fields, it is leading major research projects related to AI technology, participating in various development projects, including next-generation AI semiconductors, PIM (Processing-In-Memory) technology, and future semiconductor devices, and conducting main hardware design for AI systems including CPU and NPU.

Research Team from Department of Physics and Chemical Engineering and Materials Science at Ewha Suggests a Strategy to Enable Exciton Funneling and Boost Visible Light Emission in 2D Inorganic Semiconductors A joint research team at Ewha reports rapid transfer of photogenerated excitons and enhanced light emission from 2D inorganic semiconductors integrated with blue-fluorescent organic molecules. The results of the study, which highlights a strategy to develop a new type of optoelectronic devices, were published in the online edition of Advanced Science (IF: 16.806), a world-renowned academic journal within the top 4.4% in the field of materials science, on June 16 (Thu.). (from left) Prof. Youngmin You, Prof. Dong-Wook Kim, Dr. Soyeong Kwon The team led by Professors Dong-Wook Kim at the Department of Physics and Youngmin You at the Department of Chemical Engineering and Materials Science confirmed the enhancement of luminescence due to exciton transfers in heterostructure interfaces comprised of two-dimensional semiconductor transition metal dichalcogenides (TMD) and fluorescent organic molecules. Professor Kim fabricated heterostructures by stacking evaporated thin films of DY1 fluorescent molecules on TMD MoS2 monolayers. The DY1 fluorescent molecules used in the process were obtained by the team led by Prof. You during the team’s OLED development researches. Optical characterizations and probe-based surface charge distribution measurements revealed exciton transfer from DY1 molecules to the MoS2 monolayers, which led to 1.7-fold enhanced light emission from MoS2. It has been reported that charge transfer rather than exciton transfer is dominant at the interfaces of different TMD materials. This work successfully demonstrated exciton transfers in the hybrid heterostructures by stacking fluorescent organic molecules on TMDs. The team could also propose a way to identify the transfer process of charges and excitons, based on the complementary use of measuring optical properties and analyzing scanning probe microscopes.

Dr. Soyeong Kwon at the Department of Physics remarked as the first author of the paper, “Given the various trials and errors as well as numerous difficulties that I went through while studying the novel research subject of organic and inorganic heterostructures over the last two years of my Ph.D. course, I feel an even deeper sense of satisfaction and fulfillment. I also hope that our findings will be followed by many follow-up studies.” The paper, titled “Exciton Transfer at Heterointerfaces of MoS2 Monolayers and Fluorescent Molecular Aggregates,” was conducted through collaborative research by the Department of Physics at Ewha (Professor Seokhyun Yoon and Taeyoung Choi), the Institute of Basic Science at Sungkyunkwan University (Professor Ji-Hee Kim and Ki Kang Kim), and the Department of Physics at Chungnam National University (Professor Ki-ju Yee), with support from the National Research Foundation of Korea and the Institute for Basic Science. Professors Dong-Wook Kim and Youngmin You, the corresponding authors of this paper, are supported by the Basic Research Laboratory grant.
