The Effect of Buffer Layer on ZnO Nanorods on PES Substrate.

Abstract

In general, growing ZnO nanorods with the hydrothermal method requires the deposition of ZnO buffer layers. This is the most essential step, because the morphology of ZnO nanorods is strongly influenced by the buffer layer on a flexible substrate. In this work, we study the effect of the buffer layer when ZnO nanorods are grown. ZnO nanorods were grown on ZnO-buffered PES substrates with the hydrothermal method. As a result, it was found that the ZnO buffer layer using PLD had excellent characteristics compared with the ZnO buffer layer using sputtering.
