Título :	First principles study of electronic and optical properties of the chromium doped BGO crystal

Resumen:	Ab-initio calculations based on density functional theory have been employed to study electronic properties of Cr doped Bi4Ge3O12 (BGO), as well as its optical absorption spectra in ultraviolet region. Two different situations have been analyzed: when the Cr is situated at the Ge position (Cr4+), and when it resides at the Bi site (Cr3+). For each case the band structure and absorption spectra were calculated, and the Cr contributions identified and interpreted. Comparison with the experimental data indicates that the Cr enters both the Ge and Bi sites during the doping.
