Copper(I) oxide micro-cubical structures formation by metal organic chemical vapor deposition from copper(II) acetylacetonate

The copper oxide films were deposited by decomposition of copper(II) acetylacetonate precursor in a hot wall horizontal flow tubular furnace by chemical vapor deposition method. The obtained data revealed change in phase of the deposits from crystalline copper(I) oxide (Cu 2 O) to copper(II) oxide (...

Description
Summary:The copper oxide films were deposited by decomposition of copper(II) acetylacetonate precursor in a hot wall horizontal flow tubular furnace by chemical vapor deposition method. The obtained data revealed change in phase of the deposits from crystalline copper(I) oxide (Cu 2 O) to copper(II) oxide (CuO) structures on increasing the substrate temperature from 195 to 430 °C. The scanning electron microscope images showed the formation of mono-dispersed micron-sized Cu 2 O cubical structures. The Cu 2 O micro-cubes were observed to have a comparatively higher optical transmittance than CuO film in the visible spectral region. The Cu 2 O micro-cubical films are expected to underlie the potential use as cost effective transparent conducting oxide electrode in solar cell applications.
