Spin based properties, applications, and devices are commonly related to magnetic effects and to magnetic materials. However, we established that chiral organic molecules or chiral inorganic materials can act as spin filters for photoelectrons transmission, in electron transfer, and in electron transport. The effect, termed Chiral Induced Spin Selectivity (CISS),1 has interesting implications for the production of new types of spintronics devices2 and on the importance of chiral molecules in biological systems.3 The basic effect, and its mechanism, applications and implications, will be presented.4
