Anticipated Application as Next-Generation Spintronics Device
A research team led by Professor Kim Young-hoon from the Department of Energy Engineering at Hanyang University has developed a chiral perovskite material with the highest asymmetry in the world, which can be used in next-generation spintronics devices.
This research was conducted in collaboration with Professor In-Hyuk Park's team from the Graduate School of Analytical Science and Technology at Chungnam National University. The team successfully synthesized a chiral perovskite based on a new central metal, palladium (Pd), achieving a world-leading asymmetry (distortion index = 0.128), surpassing the previous highest distortion index of 0.08 for existing materials.
Chiral perovskite materials are gaining attention as next-generation spintronics materials due to their ability to selectively absorb different circularly polarized light and control the spin direction of charges, thanks to the asymmetry caused by their twisted lattice.
The material developed by the research team overcomes the limitations of existing materials, allowing efficient control of polarization and spin polarization, and demonstrates excellent atmospheric stability, increasing its potential for application in next-generation spintronics devices.
This research was supported by the Ministry of Science and ICT's Digital Research Innovation Leading Institution Development Project, Basic Research Laboratory, and Outstanding Young Researcher Support Project. It was published on June 5th in the 'Journal of the American Chemical Society (JACS, IF 15.0)', a world-renowned journal with a long tradition and authority in the field of chemistry.
