Abstract
In this work, α-form and β-form of copper (II) phthalocyanine (CuPc) were used for fabrication of OFET devices and the corresponding electrical performance was studied. OFETs with α-form CuPc were found to exhibit better device performance with an average mobility of 4.7(±1.0) × 10–3 cm2V−1 s−1 compared with β-form with an average mobility of 0.9(±0.2) × 10–3 cm2 V−1 s−1. The better device performance of α-form CuPc OFETs was attributed jointly due to thinner active semiconductor and better film uniformity in α-form CuPc OFETs over β-form devices.
