| Title: | Effects of transition metal impurities in alpha alumina: a theoretical study |
| Authors: | Dantas, Jeânderson de Melo Lima, Adilmo Francisco de Lalic, Milan V. |
| Issue Date: | 2010 |
| Resumo : | Ab-initio calculations based on density functional theory have been employed to study the electronic and some optical properties of Y and Nb doped α-Al2O3 with corundum structure. The Nd presence elevates the static dielectric constant of the pure alumina, but changes significantly its band offset. Doping with Y preserves the band gap value and increases slightly the dielectric constant of the pure alumina, thus showing a potential to be used in semiconductor industry. |
