Abstract

Pentacene-based organic thin-film transistors with solution-process hafnium oxide (HfO_x) as gate insulating layer have been demonstrated. The solution-process HfO_x could not only exhibit a high-permittivity (K = 11) dielectric constant but also has good dielectric strength. Moreover, the root-mean-square surface roughness and surface energy (γ_s) on the surface of the HfO_x layer were 1.304 nm and 34.24 mj/cm ², respectively. The smooth, as well as hydrophobic, surface of HfO_x could facilitate the direct deposition of the pentacene film without an additional polymer treatment layer, leading to a high field-effect mobility of 3.8cm²/(V. s).
