Cuprous oxide (Cu 2 O) is a p-type semiconductor with a direct bandgap of (Eg ∼ 2.17 eV) (Gou and Murphy, 2003, Wang et al., 2002, Liao et al., 2009, Scanlon et al., 2009, Hossain and Alharbi, 2013).The first attempt to use this material for PV application was done by national science foundation and joint centre for graduate studies in 1978 …

Uses. Copper oxide is an active component of many fungicides and pesticides. This compound was one of the first semiconductors to be discovered. It also demonstrates the photoelectric effect, where exposure to light causes an electric current to flow. For this reason, it is used in photoelectric cells and light detectors.

Copper oxide nanoparticles were obtained by the chemical precipitation method using NaOH and the synthetic route was performed in two stages. Typically, in the first stage, 1 g of copper sulfate (CuSO 4 ·5H 2 O) was dissolved in 50 ml of deionized water in a round bottom flask under continuous stirring for 30 min. After, NaOH solution …

Copper Oxide is a natural occurring mineral found in earth's crust. It is made up of copper and oxygen atoms bonded together. Copper oxide is a brownish-yellow powder that is insoluble in water. It is used as a natural food colourant and has a bitter taste. Copper oxide is a permitted food additive in the EU and USA.

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 …

Copper oxides are unusual in two respects. First, octahedral-site Cu(II): t 6 e 3 contains a single e hole in the 3d shell, which makes it orbitally degenerate and therefore a strong Jahn–Teller ion; consequently, Cu(II) ions normally occupy octahedral sites that are deformed to tetragonal (c/a > 1) symmetry by Jahn–Teller orbital ordering. However, in …
