Investigation of annealing effects on physical properties of chemically prepared copper oxide thin films

Tailored Nanoscale Architectures for White Light Photoelectrochemistry: Zinc Oxide Nanorod-Based Copper Oxide Heterostructures

“…In this work, the formation process of copper oxide on ZnO NRs under nitrogen and air annealing conditions was first explored by scanning electron microscopy (SEM). Previous studies have shown that appropriate annealing helps eliminate impurities, enhances crystallinity, and increases the grain size of copper oxide layers grown by CBD [42][43][44]. Here, we focus on elucidating the morphological evolution of copper oxide coatings by annealing over a temperature range of 100-400 • C under air or N 2 gas conditions.…”
