| Abstract: | A method, the morphology of screen printed carbon nanotube pastes is modified using a hard hairbrush, is presented.In this way, the organic matrix material is preferentially removed.Compared to those untreated films, the turn-on electric field of the treated film decreases from 2.2 V/um to 1.6 V/um, while the total emission current of the treated increases from 0.6 mA/cm2 to 3 mA/cm2, and uniform emission site density image has also been observed. |
