solution growth and characterization of copper oxide thin films

DU Onah, EI Ugwu, BO Ekuma


Thin films of copper oxide (CuO) were grown on glass slides by using the solution growth technique. Copper cloride (CuCl ) and potassium telluride (K T O ) were used. Buffer 2 2e 3 solution was used as complexing agent. The solid state properties and optical properties were obtained from characterization done using PYE UNICAM (SP6-450) spectrophotometer.
The band gap was computed when the absorption coefficient is zero and ranges from 4.624eV to 6.205eV.
