Single-crystal field-effect transistors based on copper phthalocyanine

摘要

Copper phthalocyanine (Cu-Pc) single crystals were grown by physical vaportransport and field effect transistors (FETs) on the surface of these crystalswere prepared. These FETs function as p-channel accumulation-mode devices.Charge carrier mobilities of up to 1 cm2/Vs combined with a low field-effectthreshold were obtained. These remarkable FET-characteristics, along with thehighly stable chemical nature of Cu-Pc make it an attractive candidate fordevice applications.
