The Influence of a Magnetic Field on Organic Field Effect Transistors: Comparison between Metal-Free and Metal-Phthalocyanines — •Daniel Bülz1, Sreetama Banerjee1,2, Dietrich R. T.

Organic semiconductors are of great interest in todays electronics because of their tunable optical and electrical properties. Especially they are suitable for spintronics due to their weak spin scattering compared to inorganic materials, which results in longer spin lifetimes.

It was shown, that some of these materials respond to an external magnetic field with a change of resistivity. Furthermore, it is reported that organic field effect transistors (OFETs) are suitable to measure this dependence [1]. Therefore we here investigate OFETs made from different metal-free and metal-phthalocyanines in order to compare the influence of the metal center on the magnetic field dependence.
