As global data accumulation increases at an ever-growing rate, further miniaturization and the decrease of power consumption have the highest priority in the development of our information and communication technologies. Memory technologies available today offer a variety of methods; all have advantages but also suffer from various drawbacks. Hence, memory performance is fast becoming the key bottleneck that limits system performance.
Spin based properties, applications, and devices are commonly related to magnetic effects and to magnetic materials. However, it was recently found that chiral organic molecules act as spin filters in electron transfer processes. The new effect, termed Chiral Induced Spin Selectivity (CISS), has interesting implications for the production of new types of spintronics devices but also in electron transfer mechanisms in biological systems.
In this talk I will give a short introduction to this newly evolved research area, following which I will present our own work in the field. My focus will be on CISS based devices where chiral molecules are coupled to ferromagnetic solid state surfaces via self-assembled monolayer adsorption methodology, thus enabling room temperature logic and memory applications on the nano-scale.
