Abstract

The optical constants and thickness of TiO ₂-MnO ₂ films (with MnO ₂ concentration of 0, 1, and 5%) prepared by electron-beam evaporation are determined. A considerable dependence of the optical properties of thin TiO ₂ films on the manganese concentration is observed. It is found that thin films are indirect gap semiconductors with gap width E _g = 3. 43 eV (TiO ₂), 2. 89 eV (TiO ₂-MnO ₂ (1%)), and 2. 73 eV (TiO ₂-MnO ₂ (5%)).
