Abstract

In this thesis we perform a theoretical study on the Chirality Induced Spin Selectivity effect in the context of two-terminal measurements for realistic parameters. In twoterminal measurements on chiral molecules one of the leads is magnetized and the current is measured for opposite magnetizations. In experiment it is found that the currents for opposite magnetizations are different for finite bias voltage. We call this finite difference a magnetocurrent. The magnetocurrent is odd in bias voltage and the size of the effect of the order of a few percent. Our aim is to explain this effect through modeling junctions with interactions and the spin-orbit where we always use choose realistic parameters.
