Abstract :
We present nonmagnetic organic transistors with wideband-gap polymer:bis[(4,6-difluorophenyl)pyridinato-N, C2]-(picolinato)iridium(III) (P36HCTPSi:FIrpic) mixed heterojunctions, achieving a high stable current gain of 73 and 14% organic magnetocurrent effect over a wide range of collector-emitter voltages and an external magnetic field, respectively. We employed a substrate heating treatment technique during deposition of the mixed emitter layer to achieve low surface roughness and, consequently, improved the on-to-off current ratio of around 105.
