Abstract<\/strong><\/span><\/p>\n

The \u2018conventional wisdom\u2019 about chirality in biomolecules is that it serves as a structural motif to place chemical functionalities in defined positions and orientations that enable biologically relevant functions. While the electron spin is accepted as important in defining structure of atoms and molecules, spin based properties, applications, and devices are commonly related to materials that have unpaired electrons (paramagnetic). However, we found that chiral molecules, crystals, and films act as spin filters for photoelectrons transmission, in electron transfer, and in electron transport.<\/p>\n

The effect, termed Chiral Induced Spin Selectivity (CISS),(1)\u00a0 was found, among others, in bio-molecules and in bio-systems as well as in chiral oxides and in chiral perovskites. Its existence may explain the role of chirality in living organisms and allows new applications for chiral molecules and materials like in\u00a0 spintronics devices, (2)\u00a0\u00a0 in controlling magnetization,(3)\u00a0 and on electron transfer and conduction. It also enables the introduction of new type of catalysts, especially for oxygen related processes. We also found that charge polarization in chiral molecules is accompanied by spin polarization. This finding shed new light on spin dependent interaction between chiral molecules and between them and magnetic surfaces.(4)<\/p>\n
