Abstract
CuO nanostructures materials were prepared by thermal process using carbon charcoal assisted. The copper powder and copper sheet were mixed and covered with carbon charcoal. The starting materials and Si substrates were put in the furnace and heated at various temperatures under atmosphere of nitrogen gas. The prepared products were characterized by scanning electron microscope and X-ray diffraction technique and then studying for changing of the electrical resistance with temperature. The results revealed that the nanostructures of material consisting of CuO and Cu2O phase and the electrical resistance was changed with temperature.
