Abstract
The n-type organic thin film transistors (OTFTs) employing zinc hexadecafluorophthalocyanine (ZnPcF16) as the active layer
and para-hexaphenyl (p-6p) as the inducing layer have been demonstrated. Compared with the ZnPcF16-based OTFTs without
the p-6p inducing layer, the charge carrier field-effect mobility (μ) of the ZnPcF16/p-6p OTFTs is greatly improved. The mobility
of the ZnPcF16/p-6p OTFTs is 1.30×10-2 cm2/V·s. The improved performance is attributed to the introduction of p-6p to form a
highly oriented and continuous film of ZnPcF16 with the molecular π-π stack direction parallel to the substrate..
