ABSTRACT
Figure 13.6 (a) SEM side view of the ZNWs grown on the Ga-doped ZnO/Si3N4/SiO2/Si substrate, (b) emission current density (J) vs. electric field (E) (J-E) characteristics of ZNWs. The inset shows FN plots of ln(I/V2) against (1/V). Reproduced from Adv. Funct. Mater., 13, pp. 811-814 (2003). Copyright © 2003, Wiley-Vch Weinheim [31]. Abbreviation: FN, Fowler-Nordheim.
