A method for the controlled direct growth of highly crystalline ZnO nanorods on a paper substrate is described. Despite the complexity and surface roughness which paper naturally presents, adequate surface modification enhances ZnO nanorod alignment and uniformity in growth. Large scale synthesis is also demonstrated. Hybrid PN junction diodes, also on paper substrates, show application toward flexible electronics.
