Spintronic components based on chiral molecules - From single to ultiples elements (CHIRAL)

Basic data for this project

Description

The project is aiming for the realization of more complex prototypical spintronic devices and for a deeper understanding of the microscopic basis of the CISS effect. In the first funding period it could be shown for helicene that the sign of the spin polarization is connected to the handedness of the molecules. Furthermore, a simple way to achieve optically and electrically induced local magnetic memory was established and the magnetization without current or magnetic field could be demonstrated. The second phase will focus on the realization of multiple element devices, including reading heads and spin detectors, and introduce the new concept of CISS-spinterface for generating magnetic matrix domains and their manipulation. Bottom-up dip-pen lithography will be evaluated for the fabrication of multiple element devices. In a high risk work package spin coherence effects in CISS devices will be investigated which may lead to the observation of spin interferences. Then the realization and characterization of novel quantum devices at room temperature will conclude the project. The experimental studies will be complemented with extensive theoretical modeling combining first-principle and model Hamiltonian approaches.
