WebSep 4, 2024 · Calculations predict that a dynamical Rashba effect could enhance the lifetimes and diffusion lengths of photocarriers in perovskite solar cells. The dynamical Rashba effect is characterized by spin splittings in the band structure at elevated temperatures, induced by local structural disorder. WebDec 5, 2024 · In 1964, Solomon Pekar and Emmanuel Rashba observed that nonuniform magnetization couples the electron spin to its orbital motion. It turns out that, for an electron in a Néel antiferromagnet, a smooth texture of the staggered magnetization also produces spin-orbit coupling.
WebJul 30, 2024 · We demonstrate this using a suite of spatially resolved and depth-sensitive techniques, including circular photogalvanic effect, inverse spin Hall effect, and multiphoton microscopy, that are supported by first principle calculations. Our work suggests using surface Rashba states in these materials for spintronic applications.
