Calculation of Electronic and Optical Properties of Doped Titanium Dioxide Nanostructure
By means of first principles calculations we show that both rutile and anatase phases of bulk TiO2 doped by S, Se or Pb can display substantial decreasing in the band gap (up to 50%), while doping by Zr does not sizably affect the band-gap value. Moreover, the absorption edge is shifted (up to 1 eV) to the lower energy range in the case of TiO2 doped by S or Pb that opens a way to enhancin...
متن کاملAb initio study of the Surface Passivation influence on electronic and optical Properties of (001) SbNSr3 anti-perovskite Surface
In this research, the electronic and optical properties of the (001) surface of SbNSr3 with SbSr and NSr2 terminations and surface passivation impact on electronic properties were investigated. The calculations were done within density functional theory and using pseudo-potential method. HSE hybrid functional was used for exchange correlation potential. The surface calculations were performed t...
متن کاملSynthesis and characterization of Lanthanum doped Bismuth Ferrite
B1-xLaxFeO3 (x = 0.0, 0.025) crystallites were prepared by chemical solution route. XRD analysis confirmed the phase formation of the materials. Thermal characterization was done by DSC-TGA to confirm crystallization and thermal behavior for phase development. Morphological studies by FESEM showed the agglomerated nature of the ferrite...
