Abstract :
The effect of nitrogen doping on optical properties and electronic structures of SrZrO3 (SZO) films was investigated both experimentally and theoretically. A shift of the absorption edge to the longer wavelength, i.e., the narrowing of the band gap caused by nitrogen doping was observed. The first-principles calculations revealed that the band gap reduced in nitrogen-doped SZO because of the localized N 2p states above O 2p states and the bottom of conduction band of Zr 4d shifting to a lower energy.
