The Electronic Structures and Optical Properties of Electron Tuned Fe-Doped SnO2 Materials

الملخص EN

By means of the full-potential linearized augmented plane-wave method (FP-LAPW), the electronic structures and optical properties of Sn15FeO32 with electron-injection are studied.

The results show that Fe-doped SnO2 materials are all direct transition semiconductors.

The Fermi level goes into conduction band gradually and the band gap decreases with the increase of electron injection.

The peaks of optical properties, such as the imaginary part of dielectric function and absorption spectra, change greatly at low energy.

The absorption spectra exhibit blue shift, and the optical absorption edge increases, which are consistent with the change of the band gaps.
