abstract = "Here, we report on high-performance top-gated poly(3,3‴-dialkyl- quarterthiophene) (PQT-12) organic thin-film transistors (OTFTs) with reverse-offset-printed (ROP) silver (Ag) source/drain (S/D) electrodes. OTFT devices with ROP S/D electrodes using Ag nanopaste show higher performance (∼0.01cm2/Vs) than those fabricated by vacuum electron beam evaporation with conventional photolithography and a standard lift-off process (∼1×10-3cm2/Vs). This dissimilarity is attributed to the higher work function (-4.9eV) of the ROP Ag electrode due to AgO formation on the Ag surface during thermal annealing. This results in a low interfacial hole injection energy barrier between the S/D electrodes and the PQT-12 semiconductor.",
