Abstract
The magnetoresistance (MR) of organic field effect transistors has been studied. Both pentacene film and tetracene single crystal devices exhibit negative MRs of up to 0.57% at 9 T. This effect has been observed between 150 and 300 K and is temperature dependent. The phenomenon may result from the action of the magnetic field on the hopping transport of carriers. However, the possibility of a magnetocapacitance effect that would increase the number of carriers cannot be ruled out.
