Inversion of magnetoresistance in organic semiconductors

Inversion of magnetoresistance in organic semiconductors

We report that organic semiconductors such as alpha-sexithiophene (alpha-6T) have magnetoresistance (MR) with unexpected sign changes; depending on applied voltage, temperature, and layer thickness, the resistance may either increase or decrease upon application of a small magnetic field (
