New perovskite system extends room-temperature spin polarization via successive quantum wells

A research team led by Lu Haipeng, a professor in the Department of Chemistry at The Hong Kong University of Science and Technology (HKUST), has achieved a breakthrough in preserving spin information for optoelectronic technologies. The team has developed a perovskite chiral multiple quantum-well system that maintains spin polarization approximately 300 times longer at room temperature. The study opens new…
