Abstract

N-type C60 thin film transistors with heterojunction were fabricated by introducing copper phthalocyanine (CuPc) modifying layer between polymer dielectrics and C60 semiconductor. Comparing with conventional organic thin film transistors (OTFTs) based on single C60 layer, such devices can not only boost the electron mobility up to 3 times, but also well control threshold voltage VT and off current Ioff by optimizing CuPc thickness. The performance improvement can be attributed to the increase of free electron carriers by the dipole effect at the C60/CuPc interface, and better C60 film quality grown upon CuPc.
