Spin selectivity
WebMar 3, 2024 · In contrast, the spin polarization is smallest when the damage is farthest from the substrate and highest when the damage is located closest to the surface. 16 We posit … WebRecent experiments have demonstrated that the electron transmission yield through chiral molecules depends on the electron spin orientation. This phenomenon has been termed the chiral-induced spin selectivity (CISS) effect, and it provides a challenge to theory and promise for organic molecule–based spintronic devices. This article reviews recent …

WebChirality-induced spin selectivity (CISS) is a term that classifies a collection of experimental observations on chiral molecules. These observations were made in photoemission, Hall-type, and transport experiments (for an extensive overview, see ref ).Photoemission experiments show that a layer of chiral molecules has a different transmission probability … WebA discussion of the importance of electron spin in biological systems, such as its role in long-range electron transfer, in reactions that involve multiple electrons, and in bio-recognition, all of which arise from chiral induced spin selectivity.
WebJan 30, 2024 · Spin selectivity physically depends on either magnetic materials with strong internal magnetic fields or symmetry-breaking materials with large spin–orbit coupling (SOC). However, the spin selectivity of symmetry-breaking magnetic materials is not understood.
