Abstract: Pure gold layers are traditionally used for the fabrication of source/drain bottom contacts of high performance short channel pentacene transistors. In this work, these layers are successfully replaced by low cost metallic bilayers, consisting of a thick aluminum layer with a good electrical conductivity covered by a thin noble metal layer (gold or palladium) providing good charge injection into the organic semiconductor. Corresponding pentacene transistors with 5 mu m channel length achieve saturation mobilities in the range of 0.4-0.5 cm(2)/(V s), comparable to those of reference pentacene transistors based on 30 nm thick pure gold bottom contacts, but for a metal cost down to 5% of that of the reference transistors.
