Abstract

Two simple, safe and environmental friendly chemical solution methods which are suitable to mass production, applicable at low temperatures and cost effective, were used to prepare homogenous nano-structured cupric oxide (CuO) films. By using different types of substrates (glass, quartz, Cu foil and Si) and techniques various types of CuO nanostructures (plate, needle and network like) were produced. The products were characterized by scanning electron microscopy, X-ray diffraction and temperature dependant dark electrical resistivity measurements in order to investigate the effects of substrate on morphology, crystallographic structure and electrical properties of the films. From these characterizations it was seen that there are significant differences in the morphological, crystallographic, structural and electrical properties of the nanostructures that were produced by different techniques and/or on different substrates. Besides, growth mechanisms of CuO films have been investigated. © 2011 Elsevier Ltd and Techna Group S.r.l.
