3.1 Structural Observation:
To calculate the structural, optical properties and electronic properties of both pure SrTiO3 and Ag doped SrTiO3 compounds space group Pm3m, as the position of atoms throughout the supercell of both pure SrTiO3further Ag doped SrTiO3 as seen in figure seen in figure show shown in Fig 1 (a) & (b) respectively Sr: (0, 0, 0), Ti:\((\frac{1}{2},\ \frac{1}{2},\ \frac{1}{2}\ )\) and O: (\(\frac{1}{2}\),0,\(\frac{1}{2}\)) .
