The Seebeck effect of ZnO nanowires has been investigated with the future aim of building thermoelectric devices based on nanowire arrays for energy harvesting and using them in low-power portable electronics and autonomous sensor systems. Quasi monodimensional (1D) ZnO nanowires have been deposited on alumina substrates according to the recently proposed thermal evaporation process, which involves Vapour-Phase and Vapour-Liquid-Phase growth mechanisms. The Seebeck coefficient of ZnO nanowires has been successfully measured with a purposely-developed experimental set-up, confirming that the ZnO nanowires exhibit high thermoelectric coefficient. © 2011 Published by Elsevier Ltd.

Abstract
The Seebeck effect of ZnO nanowires has been investigated with the future aim of building thermoelectric devices based on nanowire arrays for energy harvesting and using them in low-power portable electronics and autonomous sensor systems. Quasi monodimensional (1D) ZnO nanowires have been deposited on alumina substrates according to the recently proposed thermal evaporation process, which involves Vapour-Phase and Vapour-Liquid-Phase growth mechanisms. The Seebeck coefficient of ZnO nanowires has been successfully measured with a purposely-developed experimental set-up, confirming that the ZnO nanowires exhibit high thermoelectric coefficient. © 2011 Published by Elsevier Ltd.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
