- Professor Sung Wng Kim’s Research Team at the Department of Energy Science Successfully Develops New Magnetic Material
- Professor Sung Wng Kim’s Research Team at the Department of Energy Science Successfully Develops New Magnetic Material Using Anionic Electrons - Expects development and activation of magnetic materials with new principles [Image 1] Professor Sung Wng Kim, Researcher Seung Yong Lee, Professor Jae-Yeol Hwang Magnets are very important materials in everyday life, and they are applied to various fields such as hard disks and electric motors. In general, magnetic materials consist of alloys of expensive rare earth elements as the main components, but problems with the price burden and unstable supply of rare earth elements have raised the need for new magnetic materials. Research on “electride” consisting of interstitial anionic electrons has drawn attention as a silver lining for the development of new magnetic materials that do not use rare earth elements, which were considered essential components for magnetic materials, or have significantly reduced their usage. The theoretical prediction that ferromagnetic characteristics can be expressed if interstitial anionic electrons exist independently in an empty space inside the material was reported, but no way to successfully synthesize new magnetic materials had been found. The research team led by Professor Sung Wng Kim of the Department of Energy Science synthesized the world's first electride magnetic material with ferromagnetic properties and clearly discovered its principles. Professor Sung Wng Kim’s team identified for the first time in the world the existence of interstitial anionic electrons that have their own magnetic moment, located independently in the empty spaces between two-dimensional layers (interlayer). The team also succeeded in developing a 2D (two-dimensional) electride magnetic material (Gd2C), which has ferromagnetism through a strong interaction (exchange interaction) between electrons and cations within its layers. In particular, it is meaningful that the two-dimensional electride magnetic material (Gd2C) has stronger magnetic moments than conventional magnets made up of only rare earth elements (Gd) so that the application of electride materials enables the development of new magnetic materials with the same magnetic properties while reducing rare earth elements. [Image 2] A two-dimensional magnetic electride scheme. Anionic electrons located in empty spaces between layers interact with surrounding atoms with their own magnetic moments to show the ferromagnetism. This study suggests that, unlike the general principle that the rare earth element expresses magnetism, it provides a new magnetic realization principle that the interstitial anion electrons have their own magnetic moment and express magnetic properties through interaction with surrounding atoms. It is also expected to drive the study of magnetic electrides in a new direction since the results showed that the limitations of research on magnetic electride materials can be overcome and succeeded in the synthesis of an electride with ferromagnetism for the first time. Using the new principle of how magnetism is shown in electride materials proposed by this study, it is expected that the use of expensive rare earth elements needed for the synthesis of magnetic materials will be reduced and the development of magnetic materials of electrides consisting of low-cost elements will be possible. The findings were published on March 23rd in Nature Communications (IF 11.878), a world-renowned scientific journal. (https://www.nature.com/articles/s41467-020-15253-5)

- Prof. Young Hee Lee’s Research Team Successfully Materialized Ferromagnetic Semiconductors at Room Temperature
- Prof. Young Hee Lee’s Research Team Successfully Materialized Ferromagnetic Semiconductors at Room Temperature - The team synthesized two-dimensional (2D)monolayer Tungsten Diselenide (WSe2) via vanadium dopant and reported theroom-temperature ferromagnetism. [Image 1] Professor Young Hee LEE and Researcher Seok Joon YUN Diluted magnetic semiconductors, the semiconductors doped with impure magnetic elements, have been expected to play an important role in spintronics. They can control both charge and spin simultaneously, so ultra-fast, low power, and high density spintronics seems feasible. Nevertheless, despite half a century of research, the issue of the Curie temperature (the minimum temperature at which the spins are aligned and ferromagnetic) being below room temperature and the uneven substance composition remained unsolved. If these two matters were not solved, commercialization of spintronics using magnetic semiconductors may have remained difficult. Recently, the Center for Integrated Nanostructure Physics (Researcher Seok Joon Yun, Researcher Duong Dinh Loc, Professor Young Hee Lee) located in the Institute for Basic Science (IBS) under the Ministry of Science, ICT and Future Planning, succeeded in resolving the problem. Using chemical vapor deposition, the research team synthesized vanadium-doped monolayer 2D Tungsten Diselenide (V-doped Wse2) and clearly saw that the Curie temperature is accessible above room temperature. [Image 2] The Schematic for the synthesis of V-doped monolayer WSe2 by mixing liquid W with V precursors via chemical vapor deposition (CVD). Meanwhile, the team observed the magnetic domain of monolayer V-doped Wse2 and the fact that the V-doped WSe2 reveals a Curie temperature above room temperature by analyzing the transition of the magnetic domain according to temperature and magnetization direction. It could be possible with the magnetic force microscopy (MFM), which is sensitive and can detect very small magnetic dipole moments within a nanometer. Also, through the analysis of the atomic structure by transmission electron microscopy, it was revealed that vanadium is doped and distributed evenly on WSe2 which also resolved the old problem of uneven element status. Furthermore, it was revealed that the electron density could be altered and the ferromagnetic moment could be controlled. Diluted ferromagnetic semiconductors at room temperature produced by the research team made wafer-sized synthesis possible. Due to this reason, it is expected to be commercialized as soon as possible. Director Young Hee Lee, who led this research, said, “The research proved that ferromagnetic semiconductors at room temperature can exist within a thin material at the level of a monolayer, which hadn’t been discovered for the past half a century. Through the outcome of this research, we expect to bring about a breakthrough in the application of spin electronics and quantum computers.” [Image 3] Photos of monolayer V-doped WSe2, depending on temperature and magnetic direction of a magnetic probe taken by magnetic microscopy The outcomes of this were published on March 11th in Advanced Science (IF 15.804), a world-renowned scientific journal.

- Professor Ji-Hee Kim and Professor Young-Hee Lee's Research Team Drive 3rd Generation High-Efficiency Solar Cell Devel
- Professor Ji-Hee Kim and Professor Young-Hee Lee's Research Team Drive 3rd Generation High-Efficiency Solar Cell Development by Implementing Photoelectronic Current Amplification - published online on March 4 (Wed.) in Advanced Materials Professor Ji-hee Kim of SKKU’s Department of Energy Science and Professor Young-hee Lee of the Nanostructure Physics Research Group (first author: Seong-tae Kim, student of the Department of Energy Science) succeeded in attaching a single quantum dot to an atomic microscope probe and amplifying the light current of a shining light. In general, only a grain of light (photon) can produce a pair of charge carrying particles (carriers). Since the extra light energy is released into heat, it is difficult to convert all of the solar energy into electricity. Under certain conditions, however, the carrier amplification phenomenon, which generates two or more carriers instead of transmitting heat from extra energy of a pair of electron hole (carriers) generated by a single photon, has been noted as a key to significantly improve the efficiency of third-generation solar cells. Although quantum dots are expected to have high carrier amplification efficiency without heat loss because the energy level can be separated to suppress electron-phonon scattering, optical measurement methods used previously to identify carrier amplification phenomena have limited applications in devices such as solar cells. Also, it was difficult to accurately analyze the carrier amplification phenomenon that occurred in one quantum dot, as conventional measurement methods allowed the study of carrier amplification only on solutions that dispersed quantum dots or even quantum dot film specimens. Therefore, the researchers devised a method of re-extracting optical carriers generated by atomic microscopes, measuring them with photovoltaic currents, and observing current changes in amplified carriers within a single quantum point. The researchers attached a sulphurized quantum dot to the apex of an atomic microscope conductive probe and accurately approached a graphene electrode with quantum dots within tens of nanometers to achieve small contact resistance and short channel distances. This structure is a vertical junction structure similar to thin-film solar cells, which enables control of the recombination rate of electron holes and can generate local light currents by increasing carrier extraction efficiency. The quantum efficiency extracted from the measured local light current reached 99%, the highest efficiency of the quantum dot carrier amplification reported to date, and achieved the lowest carrier amplification critical energy. The photoelectric amplification using atomic microscopy developed by the research team is a new and unique evaluation technology that can directly evaluate the photoelectric amplification phenomenon in low-dimensional devices. It is expected that it will secure leading infrastructure technology in developing third-generation high-efficiency solar cells that utilize photoelectric amplification in the future and will serve as a foundation for creating new industries. This paper was published online on March 4 (Wed.) in Advanced Materials (Effectiveness Index=25.809) which is within the top 2% of international journal rankings in applied physics.
