title: ZnO nanowires grown on carbon cloth for flexible cold cathode.
abstract: Nanostructures grown on carbon cloth are recently attracted great interests for flexible field emitter and cold cathode. In this paper, we report high-aspect ratio ZnO nanowires grown on carbon cloth by a low-temperature solution chemical approach that can be used as a flexible and high performance cold cathode. The carbon cloth is covered by outward-grown ZnO nanowires uniformly and densely with spiny structures. The hybrid structures exhibits a turn-on electrical field of 4.36 V/microm and a field enhancement factor of 1157, which benefit from the high-aspect ratios of both ZnO nanowires and carbon cloth. These results demonstrate a low cost and scalable approach for flexible cold cathode lighting and field emission display.
