Abstract:

Spin based properties, applications, and devices are commonly related to magnetic effects and to magnetic materials. Hence, most of the development in spintronics is currently based on inorganic materials. Despite the fact that the magnetoresistance effect has been observed in organic materials, until now spin selectivity of organic based spintronics devices originated from an inorganic ferromagnetic electrode and was not determined by the organic molecules themselves. In several studies, however, we found that chiral organic molecules can act as spin filter for photoelectrons transmission, in electron transfer, and in electron transport.  

I will present results from several recent experiments demonstrating the CISS effect and devices based upon as well as an explanation for the phenomenon. The implications related to electron transfer in biology will be discussed as well as spintronics related applications.
