Abstract

Copper phthalocyanine (CuPc)-based thin film transistors were fabricated using CuPc films grown under different deposition pressure (P_dep) (ranging from 1.8 × 10^-4 Pa to 1.0 × 10^-1 Pa). The transistor performance highly depended on P_dep. A field-effect mobility of 2.1 × 10^-2 cm²/(V s) was achieved under 1.0 × 10^-1 Pa. Detailed investigations revealed that P _dep modulates the molecular packing and orientation of the organic films grown on a SiO₂/Si substrate and influences the charge transport. Furthermore, from a device physics point of view, contact resistance of the fabricated transistors decreased when P_dep increased, which was beneficial in reducing energy consumption.
