Abstract

In this work the performance of organic field-effect transistors (OFETs) using Copper Phthalocyanine (CuPc) and Titanyl Phthalocyanine (TiOPc) as active layers is compared. Current/Voltage measurements were first performed in vacuum and later under ambient conditions. The highest hole mobility μvac = (1.5 ±0.6) ×10^-3cm²/Vs was obtained for the CuPc OFETs. The mobility remained constant within the error bar after exposing the OFETs to atmosphere (μatm = (1.2 ± 0.2) × 10^-3 cm²/Vs). For the TiOPc transistors a hole mobility of μvac = (7.2 ±4.0) ×10^-5 cm²/Vs was found in vacuum. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
