Abstract

We investigated the effect of Cr thickness on the electrical properties of triisopropylsilyl pentacene organic thin-film transistor (OTFT) employing suspended source-drain electrode. With Cr thickness of 10 nm, the field-effect mobility, on/off ratio and subthreshold slope were $0.017\;cm^2/Vs$, $8.78\;{\times}\;10^3$ and 10 V/decade, respectively. By increasing the Cr thickness to 100 nm, the fieldeffect mobility was increased to $0.032\;cm^2/Vs$, on/off ratio to $1.12{\times}10^5$ and subthreshold slope to 1 V/decade.
