Lim Jung-yeon, a master's student (2nd year) in the Department of Electronic Engineering at the Graduate School of Kookmin University (advisor: Professor Choi Sung-jin), has published a paper as the first author in the world-renowned scientific journal ACS Applied Materials & Interfaces (IF: 8.3), and the research has been selected as the cover article (Cover Article) of the journal. ACS Applied Materials & Interfaces is a highly influential international academic journal in the field of materials and electronic devices, and cover articles are awarded only to outstanding research that represents the issue. In particular, it is extremely rare for research led by a master's student to be selected as a cover article.
Implementing an “electronic fingerprint” that cannot be replicated in a single transistor: The research team designed and fabricated a dual-gate transistor using carbon nanotubes (CNTs) as the channel material, successfully implementing a physically unclonable function (PUF) that prevents replication. This transistor possesses unique electrical characteristics for each device, enabling it to function as an ‘electronic fingerprint’ that is virtually impossible to replicate or hack. Additionally, while existing PUF devices generate simple values of 0 or 1 using a single transistor, this study enables the distinction of four states (Quaternary State) within a single device, allowing for twice as much information to be generated within the same area.
From theory to actual production and verification: The research team did not stop at theory but directly produced hundreds of CNT transistors on an 8-inch wafer and completed experiments. The devices operated stably even at high temperatures (100°C) and demonstrated the ability to reliably generate thousands of unique security keys.
The technology has potential applications in smartphones, automobiles, the Internet of Things (IoT), biometric authentication systems, and other electronic devices where tamper-proof, low-power security technology is essential. This research is evaluated as a highly useful platform for developing next-generation security chips, as it simultaneously satisfies the requirements of ultra-small size, high security, and high reliability. This research was conducted with support from the Ministry of Science and ICT and the National Research Foundation of Korea's Mid-Career Researcher Support Program and was officially published as a cover article in the July 2025 issue of ACS Applied Materials & Interfaces.
