Abstract

Spin based properties, applications, and devices are commonly related to magnetic effects and to magnetic materials. However, we found that chiral organic molecules act as spin filters for photoelectrons transmission [1]  in electron transfer [2] and in electron transport [3]  .

The new effect, termed Chiral Induced Spin Selectivity (CISS) [4,5]  has interesting implications for the production of new types of spintronics devices [6]  and on electron transfer in biological systems.  The effect was found in bio-molecules and in bio-systems [7]. The basic effect will be explained and various applications and implications will be discussed.
