Copper Oxide
Copper oxides exist in two different forms: cupric oxide (CuO) and cuprous oxide (Cu 2 O), depending on the valence state of copper. Here, we concentrate on CuO. The CuO is a p-type semiconductor with an indirect band gap of 1.2 – 1.9 eV (see Ray, 2001; Koffyberg and Benko, 1982; Marabelli et al., 1995).The crystal structure of CuO is in the monoclinic …
