The phenomenon of chirality-induced spin selectivity (CISS) has been studied for nearly two decades, where chiral organic molecules enable the selective transmission of electrons spin-polarized along the direction of electric current. Recent studies have expanded the concept of spin selectivity to chiral inorganic crystals, offering promise for magnet-free spintronics and other applications.
Quasi-persistent Spin Texture in Chiral Materials
One intriguing feature of chiral materials is the presence of a quasi-persistent spin texture (PST) in reciprocal space, which suggests its exact understanding and additional experiments are required to validate this hypothesis.
