Research of Professor Suyeon Cho-led Team Selected as the Cover of World-Renowned Scientific Journal Chemical Reviews
The research team led by Professor Suyeon Cho of the Department of Chemical Engineering and Materials Science has published a groundbreaking review paper on designing low-dimensional materials (LDMs) to build ultra-high-speed, high-density semiconductor devices required for the Fourth Industrial Revolution. The research paper by Professor Cho’s team has been selected for the cover of the international scientific journal Chemical Reviews (IF: 72.087). It was co-authored by Seungyeon Lee from the Graduate Program in System Health Science and Engineering of Ewha’s BK 21 FOUR program, in collaboration with the team led by Professor Yang Heejun of KAIST’s Department of Physics. The paper, titled “Phase-Engineering of 2D Materials,” was published online on August 17, 2023 (Thu.).
The Fourth Industrial Revolution, characterized as ICT technologies ranging from AI and 5G mobile communication services to autonomous vehicles and robots, is closely linked to the development of system semiconductors. To realize the development of ultra-small, high-performance system semiconductors, biomimetic semiconductor devices with ultra-low power, high density and high response speed are attracting great expectations as an innovative way to reduce the load incurred by communication and calculation.
With the aim to develop next-generation semiconductor devices with high density and high response speed, such as biomimetic semiconductor devices, the paper published by Professor Cho’s team reported various research findings and introduced their significance in terms of controlling diverse structural phases and movements of low-dimensional materials at the nanoscale. The paper also reported that numerous follow-up studies on low-dimensional materials will be able to utilize not only metal-insulator transitions but also magnetism of 2D materials, strongly correlated band structures and phase transitions resulting from changes in topological relations. Notably, the paper verified that structural phase engineering using electrical, optical and plasma post-processing could form a new low-dimensional phase boundary, possibly leading to the development of new materials. The utilization of this technology is expected to enable fast data processing, which may enhance the ease of use for technologies requiring high response speed in real time, such as 5G service-based, massive real-time services and autonomous vehicle technologies.
