[ 1 ] - 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...
[ 2 ] - مکانیسم تولید و ویژگیهای تابش پرتوی ایکس پارامتری حاصل از الکترونهای نسبیتی در یک بلور
In this paper, the parametric X-ray radiation (PXR) spectral-angular distribution in the framework of the dynamical and kinematical diffraction theory was investigated in details. It is shown that dynamical diffraction effects can be increase with intensity of radiation, increase threshold energy saturation and the change in polarization of the radiation. Therefore, some unique properties of P...
