Recent progress on growth and device development of ZnO and CuO nanostructures and graphene nanosheets

Recent progress on the growth of zinc oxide (ZnO), copper oxide (CuO) and graphene nanosheets is presented and discussed. We here restrict the discussion to the hydrothermal low temperature growth regime. In view of this the most critical and important parameters for obtaining nanostructures with desired morphology are discussed and presented. Among all parameters, the temperature and the pH during growth were chosen due to their strong role in affecting the produced nanostructures. The application of this method to non-conventional substrates e. g. paper, is demonstrated. Different devices are fabricated using the grown material and their performance is discussed.
