Optimizing OFETs properties for spintronics applications

Overview & Synopsis

In this thesis, charge carrier transport in conjugated polymers is studied with the aim to identify organic electronics devices properties suitable for applications in organic spintronics. We investigate planar samples, in a lateral geometry, which offer the possibility to study transport properties under the application of different stimuli and to detect long-range spin transport in OSCs. In this configuration, well-established criteria must be satisfied to realize diffusive-like transport of a spin-polarized current through an organic material. We analyse these criteria and find possible materials properties solutions. The outcome is the realization of organic field-effect transistors with properties ad hoc for spintronics applications.
