| Abstract | ||
| Thin films of cuprous oxide Cu2O have been prepared using spray pyrolsis technique. Experimentally, the optical energy gap of Cu2O was about 2.2eV. To achieve and estimate an accurate Eg value, there was problem in the selection of exact tangent point. To overcome this problem, Newton-Raphson method and mean-value theorem were used. It was found that the mean-value theorem can predict correlated nearly satisfactory Eg value than the other method. | ||
