This article discusses recent advancements in understanding topological phase transitions in 2D organometallic lattices. Researchers, led by Prof. Li Xingxing at the University of Science and Technology of China, utilized lactam-lactim tautomerization to reversibly control the topological properties of these lattices. This process enabled them to alter the electronic band structure and spin polarization direction, leading to a change in the Chern number. The study offers potential applications in creating materials for spintronics and quantum computing due to their dissipationless electron transport properties.
