To overcome these limitations, researchers are exploring new approaches, particularly spin-based technologies. However, manipulating spin states at room temperature remains extremely difficult due to the rapid spin decoherence process.<\/p>\n<p>To address these challenges, the HKUST research team developed a novel perovskite chiral multiple quantum-well system that enables an efficient \u201cspin cascade\u201d process. Using a two-step seed-assisted crystallization approach, the team constructed well-oriented quantum wells with varying widths and continuous intrinsic chirality across two-dimensional (n = 1), quasi-two-dimensional (n = 2, 3, 4, \u2026) and three-dimensional (n = \u221e) perovskite phases.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>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.
