▲Non-volatile 6G switch based on two-dimensional materials
Professor Myung-Soo Kim and his research team at UNIST have developed a two-dimensional semiconductor-based analog switch.
Zero standby power, high energy efficiency… Potential for next-generation 6G systems
A semiconductor device for 6G communication that is highly electrically efficient and can process signals quickly and accurately has been developed, contributing to the commercialization of 6G communication.
Professor Myung-Soo Kim of the Department of Electrical and Electronic Engineering at UNIST announced that he has developed a low-power, ultra-high-speed analog switch in collaboration with researchers from the United States, France, and Israel.
The results of this study were introduced on the 31st in the 'Research Briefing' section of Nature Electronics, a sister journal of Nature and an authoritative journal in electrical and electronic engineering, as "the first case with a high possibility of commercialization among electronic devices made of two-dimensional semiconductor materials."
Analog switches are semiconductor devices used to select and transmit or block radio waves. They have been widely used in data communication and hyper-connected systems to switch between various frequency bands and to transmit and block signals between antennas and reconfigurable wireless communication systems.
In order to support wireless environments such as autonomous driving, AR, and VR through 6G communication, it is necessary to solve the problem of standby power consumption when existing diode or transistor-based analog switches are not in operation.
Professor Kim's research team announced that they have developed an analog switch with zero standby power consumption using molybdenum disulfide (MoS2), a two-dimensional semiconductor material.
This switch △operates in the terahertz high frequency range to meet the data transmission speed of 100 Gbit/s, which is the data transmission speed required for IEEE 6G communication, and △can also support complex signal modulation technology for implementing uninterrupted AR/VR △Satisfies the maximum transmission speed of 100 Gbit/s in various modulation technologies, and can process it with a low error rate and high signal-to-noise ratio.
Professor Myung-soo Kim explained, “Communication devices for 6G technology must be able to support complex modulation technologies while satisfying the data transmission speed of 100 Gbit/s and the operating frequency conditions in the terahertz (THz) range,” and added, “This research will contribute to the commercialization of 6G communication systems by developing low-power communication devices that can reduce battery usage while satisfying ultra-high-speed communication conditions.”

European Patent Applications Surpass 200,000 for the First Time… South Korea Maintains 5th Place, Led by Batteries and Telecommunications
According to the European Patent Office (EPO)'s 'Technology Dashboard 2025', European patent applications last year reached 201,974, surpassing 200,000 for the first time. Korean companies and inventors filed 14,355 applications, representing a 9.5% increase from the previous year and maintaining 5th place by country. Battery, digital communication, and semiconductor technologies led the growth, with Samsung ranking as the top EPO applicant for the second consecutive year and LG reaching 3rd place. The presence of major domestic cities such as Seoul, Suwon, and Yongin was also confirmed. It was also revealed that Korea's European patent strategy is expanding beyond individual technologies to span the entire industry.
