Abstract

Large-area, roll-to-roll fabrication of thin-film circuits demands layer thickness uniformity over large areas. Previously, a 10-nm-thick dry bi-layer dielectric based on aluminium oxide (AlOx) prepared by UV-ozone oxidation and n-octylphosphonic acid (C8PA) monolayer prepared by vacuum evaporation has been developed for organic thin-film transistors (OTFTs). Here we compare such OTFTs to similar transistors that incorporate ALD-AlOx/C8PA bi-layer.
