Abstract
Recent studies reveal an interesting surface-controlled conduction in the wide-bandgap single-crystalline GaN nanowires (NWs). The surface depletion and built-in electric field inherent to the NWs have led to the high-gain (long-lifetime) photoconduction and size-dependent transport properties. Efficient and selective sensing for ultraviolet light, gaseous and biological molecules based on the novel surface nature of nanostructure is presented. © Springer-Verlag Berlin Heidelberg 2012.
