AEM is a prestigious open-access journal published by Wiley in the field of electronic devices and materials research. It covers a wide range of topics including electronic devices/materials, device physics, micro/nano electromechanical systems, and organic electronics. The specific content of the paper selected as the cover of the AEM issue is as follows: In the April 2025 issue, [first author Jaeseung Woo] proposed and implemented a novel Dual-Layer-Per-Array computation scheme in an array of ferroelectric tunnel field-effect transistors (FeTFETs) for large-scale neural network implementation. Thanks to two independently controllable current regions, dual-layer vector-matrix multiplication operations can be performed within a single FeTFET synapse array. This enables the implementation of the same neural network using only half the area compared to conventional neuromorphic hardware.

A paper by researchers Park Jong-hyuk and Kim Sung-jun from the Three-Dimensional Integration and Device Lab (TIDL), led by Professor Wooyoung Choi, has been selected as the cover article for the February 2025 issue of Advanced Intelligent Systems (AIS). AIS is a prestigious journal that covers innovative research in artificial intelligence, robotics, smart sensors, and autonomous systems, encompassing both theoretical and experimental studies aimed at advancing next-generation intelligent systems. The specific details of the cover-selected paper in this AIS issue are as follows: ​In the February 2025 issue, a neuron circuit incorporating a Compensated Current Mirror (CCM) was proposed by first author Park Jong-hyuk, effectively addressing the fan-in problem encountered in Spiking Neural Networks (SNNs). Traditional neuron circuits often suffer from nonlinearity during the Vector-Matrix Multiplication (VMM) process, leading to reduced system accuracy. In contrast, the proposed CCM circuit operates with low power consumption while maintaining high VMM linearity. These characteristics suggest that the CCM neuron circuit from this study can serve as a robust solution for achieving both high energy efficiency and computational accuracy in large-scale neuromorphic systems.

The Department of Electrical and Computer Engineering at Seoul National University's College of Engineering (Department Chair: Professor Yongtaek Hong) won multiple awards, including the Special Award and the Grand Prize in the university category at the 31st Samsung Human-Tech Paper Award. This event was hosted by Samsung Electronics and co-sponsored by the Ministry of Science and ICT and The JoongAng. In particular, the Department of Electrical and Computer Engineering received a total of 11 paper awards, including one Grand Prize and two Gold Prizes, from the research labs of Professors Byonghyo Shim, Jaehyuk Choi, Jongho Lee S, Sewoong Park, and Kyunghan Lee. As a result, the department was once again awarded the "Most Award-Winning Department in the University Category” special prize, following last year's achievement. Additionally, the "Most Paper Submissions by an Advising Professor" special prize was awarded to Professor Jongho Lee S of the same department. Among the individual awards granted in 10 categories in the university division, the Department of Electrical and Computer Engineering won the Grand Prize (prize money of 40 million KRW), which is awarded to the best paper among all categories, and the Gold Prize in the Circuit Design category and the Signal Processing category (prize money of 20 million KRW each), thereby demonstrating the best performance in both quality and quantity. Student Jihoon Moon (advisor: Professor Byonghyo Shim) was honored with the Gold Prize in the Communication and Networks category and the Grand Prize across all categories for developing a millimeter-wave (mmWave) massive MIMO system channel prediction technique utilizing multi-modal sensing. In the Circuit Design category, student Jaeho Kim (advisor: Professor Jaehyuk Choi, co-authors: Myungho Han, Dr. Jueun Bang) won the Gold Prize for developing a new Command-Aware power regulation circuit that ensures the integrity of ultra-high-density I/O signals even at high-speed operation with minimal additional power consumption by leveraging the operational characteristics of HBM memory interfaces. In the Signal Processing category, student Jihwan Kim (advisor: Professor Bohyung Han, co-authors: Junho Kang, Jinyoung Choi) won the Gold Prize for proposing the innovative FIFO-Diffusion technique, which enables the generation of infinitely long videos using video generation models, models which previously could only produce short videos. Additionally, students Juhun Shin (advisor: Professor Sewoong Park), Jonghyun Ko (advisor: Professor Jongho S Lee), and Moonjae Chae (advisor: Professor Jae-Hyuk Choi) won the Silver Prize. Students Jiseong Im (advisor: Professor Jongho S Lee), Joon Hwang (advisor: Professor Jongho Lee S), Sangmok Shin (advisor: Professor Byonghyo Shim), and Daewook Hwang (advisor: Professor Kyunghan Lee) won the Bronze Prize. Joon Hwang also received an Honorable Mention. The Samsung HumanTech Paper Award was established in 1994 with the aim of discovering young scientists among domestic and international university, graduate, and high school students who will lead 21st-century science and technology. This year marks its 31st edition, with a record 3,152 papers submitted, out of which 116 teams were awarded. The Department of Electrical and Computer Engineering at Seoul National University has consistently produced numerous award winners at the Samsung HumanTech Paper Award each year. □ Details on the awarded honors are as follows: Author Award Category Category Advisor Affiliation Jihoon Moon Grand Prize Communication & Networks Byonghyo Shim SNU ECE Jaeho Kim Gold Prize Circuit Design Jaehyuk Choi SNU ECE Jihwan Kim Gold Prize Signal Processing Bohyung Han SNU IPAI (SNU ECE) Juhun Shin Silver Prize Communication & Networks Sewoong Park SNU ECE Jonghyun Ko Silver Prize Physical Devices & Processes Jongho Lee S SNU ECE Munjae Chae Silver Prize Circuit Design Jaehyuk Choi SNU ECE Jiseong Im Bronze Prize Physical Devices & Processes Jongho Lee S SNU ECE Joon Hwang Bronze Prize Physical Devices & Processes Jongho Lee S SNU ECE Sangmok Shin Bronze Prize Communication & Networks Byonghyo Shim SNU ECE Daewook Hwang Bronze Prize Communication & Networks Kyunghan Lee SNU ECE Joon Hwang Honorable Mention Physical Devices & Processes Jongho Lee S SNU ECE Source: https://ece.snu.ac.kr/ece/news?md=v&bbsidx=56247 Translated by: Dohyung Kim, English Editor of the Department of Electrical and Computer Engineering, kimdohyung@snu.ac.kr...
