Optical constants and polarimetric properties of TcNT2aMnO2 thin films

Optical constants of TcNT2aMnO2 (MnO2 content: 0%, 1%, 5%, 10%) thin films prepared by the electron-beam evaporation technique were determined using the envelope method. The optical properties of the TiO2aMnO2 thin films were strongly dependent on the MnO2 content. The TiO2aMnO2 thin films were esta...

Description
Summary:Optical constants of TcNT2aMnO2 (MnO2 content: 0%, 1%, 5%, 10%) thin films prepared by the electron-beam evaporation technique were determined using the envelope method. The optical properties of the TiO2aMnO2 thin films were strongly dependent on the MnO2 content. The TiO2aMnO2 thin films were established to be indirect band semiconductors with the band gap energies Eg: 3.43 eV (TiO2), 2.89 eV (TiO2aMnO2 (1%)) and 2.73 eV (TiO2aMnO2 (5%)). The polarimetric properties of the TiO2aMnO2 thin films were also investigated.
