Abstract :
Copper-phthalocyanine based organic thin film transistors (OTFTs) were fabricated. Cu-Pc thin films as an active layer were deposited onto the SiO2 layer as a gate insulator by using organic molecular beam deposition system. The OTFT devices showed p-type characteristics with field-effect mobility and threshold voltage as 1.22x10-3 cm2/Vsand -40 V, respectively. The activation energy was estimated to be 0.073 eV, through the temperature dependence of carrier mobility.
