Chirality transmission
WebOct 25, 2024 · Chirality-induced spin selectivity (CISS) refers to the fact that electrons get spin polarized after passing through chiral molecules in a nanoscale transport device or in photoemission experiments. In CISS, chiral molecules are commonly believed to be a spin filter through which one favored spin transmits and the opposite spin gets reflected; that … WebMay 5, 2024 · A variety of synthetic systems involve the transmission of chiral information between the molecular-, meso- and macroscales.
