Hysteretic I-V nature of ethanol adsorbed ZnO nanorods

초록

Observation of hysteresis like I-V characteristics of ethanol adsorbed ZnO nanorod is reported. Lithographically defined gold contacts were used for electrical measurements. Prolonged exposure of ZnO nanorod in ethanol adversely affects the electrical property of ZnO nanorod due to ethanol adsorbed in deep surface traps. It produces hysteresis like I-V nature in ZnO nanorods at low applied fields. This hysteresis like property of ethanol adsorbed ZnO provides a wide scope to explore further about the sensing and non-volatile switching properties of ZnO nanorod. (C) 2013 Elsevier B.V.
