In CISS, chiral molecules are commonly believed to be a spin filter through which one favored spin transmits and the opposite spin gets reflected, i.e., transmitted and reflected electrons …
WebMar 25, 2024 · The electric field induces a spin-selective electron displacement that results in a transient spin polarization at the electric poles (δ (+) and δ (−) at the ends of the helices). The spin... WebJul 5, 2024 · Since the observation of the chiral-induced spin selectivity (CISS) effect, the strong coupling between electron spin and molecular chirality has taken front stage . The initial experiments by Naaman and coworkers ( 21 , 22 ) showed that a self-assembled monolayer of double-strand DNA molecules spin filters a current of photoelectrons on a …
WebThe spin-polarized photoelectrons were observed even when the photoelectrons were generated with unpolarized light. The observed spin selectivity at room temperature was extremely high as compared with other known spin filters. The spin filtration efficiency depended on the length of the DNA in the monolayer and its organization. D 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.
