Solution-Processed Individual Multiple-Junction Structure Self-Assembled with ZnO Nanowires for UV/Blue Detection

In this paper, a novel individual multiple-junction network structure is fabricated using low temperature aqueous method. In comparison with the same growth method without NaF adding, the Fluorine doped ZnO photodetector presents multiple-junction network structure and ultraviolet (UV)/Blue dual band photoresponse performances. The results indicate the method can simultaneously promote self-assembled growth and improve the photoresponse properties. Moreover, it will provide a simple and low cost way to assemble multiple nanowires for photoresponse applications.
