| Abstract | Structural, electronic and optical properties have been calculated for Tin dioxide nanoribbons (SnO2 NRs) with both zigzag and armchair shaped edge by first principle spin polarized total energy calculation. We find that both zigzag and armchair SnO2NR have indirect band gaps. The band gap oscillates between the maximum of 3.38eV and the minimum of 1.69eV and eventually levels off to a certain value of 2.09eV for armchair nanoribbons, while for zigzag nanoribbons, the band gap oscillates between the maximum of 2.25eV to the minimum of 2.04eV and eventually levels off to 2.18eV. Our investigation further reveals that the optical absorption capacity enhanced with increasing the ribbon width for both Z-SnO2NRs and A-SnO2NRs. More interesting, when introducing Ag impurities, the optical absorption edge shift to low energy region. These findings can be a useful tool for the design of new generation of materials with improved solar radiation absorption. |
