Resende, Joao; Nguyen, Van-Son; Fleischmann, Claudia; Bottiglieri, Lorenzo; Brochen, Stephane; Vandervorst, Wilfried; Favre, Wilfried; Jimenez, Carmen; Deschanvres, Jean-Luc; Nguyen, Ngoc Duy published an article in 2021. The article was titled 《Grain-boundary segregation of magnesium in doped cuprous oxide and impact on electrical transport properties》, and you may find the article in Scientific Reports.Name: Bis(acetylacetone)copper The information in the text is summarized as follows:
In this study, we report the segregation of magnesium in the grain boundaries of magnesium-doped cuprous oxide (Cu2O:Mg) thin films as revealed by atom probe tomog. and the consequences of the dopant presence on the temperature-dependent Hall effect properties. The incorporation of magnesium as a divalent cation was achieved by aerosol-assisted metal organic chem. vapor deposition, followed by thermal treatments under oxidizing conditions. We observe that, in comparison with intrinsic cuprous oxide, the electronic transport is improved in Cu2O:Mg with a reduction of resistivity to 13.3 ± 0.1 Ω cm, despite the reduction of hole mobility in the doped films, due to higher grain-boundary scattering. The Hall carrier concentration dependence with temperature showed the presence of an acceptor level associated with an ionization energy of 125 ± 9 meV, similar to the energy value of a large size impurity-vacancy complex. Atom probe tomog. shows a magnesium incorporation of 5%, which is substantially present at the grain boundaries of the Cu2O. In the experiment, the researchers used many compounds, for example, Bis(acetylacetone)copper(cas: 13395-16-9Name: Bis(acetylacetone)copper)
Bis(acetylacetone)copper(cas: 13395-16-9) catalyzes coupling and carbene transfer reactions. Metal acetylacetonates are used as catalysts for polymerization of olefins and transesterification. Name: Bis(acetylacetone)copper
