| Summary: | Copper (II) Oxide or Cupric Oxide (CuO) is the higher oxide of copper. As mineral, it was known as tenorite. This thesis was studied the effect of annealing temperature on CuO thin films. The measurement was performed on electrial properties, optical properties and its surface topology. The CuO solution was prepared by using sol-gel method. Meanwhile, the deposition process of thin films using spin coating technique. Then, the thin films were synthesized at various temperatures in the range of 500°C until 700°C deposited onto the quartz substrates in a hot chamber furnace. The time taken for the process was about 45 minutes at a time. The general appearances of the thin films were uniform and brownish black in color after they were annealed. The measurements were performed by atomic force microscopy (AFM), photoluminescence (PL), surface profiler (SP), two point probe technique and Ultraviolet-visible (UV-Vis-NIR) spectrometer. The equipments of AFM, PL, SP, two point probe and UV-Vis was measured the surface topology, the emission of energy, the thickness of the thin films, the electrical properties and the optical properties respectively. According to the results of the overall research, the electrical properties was measured that the electrical conductivity increasing with the increasing annealing temperatures. All the experimental works were conducted according to the proposed procedure. Besides, the documented data proved all the expectations and theories related to the objectives. |
