Abstract
Aligned ZnO nanorods are grown directly on an economic, highly flexible, and environmentally benign paper substrate for the first time. Prototype photoconducting devices and PN junction diodes are fabricated based on these ZnO nanorod arrays, which can be strategically exploited for other functional devices and integrated with various optoelectronic device components. c 2010 WILEY-VCH Verlag GmbH & Co.
