Condensed Matter Seminar: Molecular Chirality and the Electron’s Spin- Their effect on Physics, chemistry and Biology
Prof. Ron Naaman, Department of Chemical and Biological Physics, Weizmann Institute
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 was found, among others, in bio-molecules and in bio-systems. 6 It has interesting implications for the production of new types of spintronics devices7,8 and on producing efficient electron transfer systems. The basic effect will be explained and various applications and implications will be discussed.
