Al-bound hole polarons in TiO2
Changes in the structural and electronic properties of TiO2 (anatase and rutile) due to the Al-doping are studied using a quantum-chemical approach based on the Hartree-Fock theory. The formation of hole polarons trapped at oxygen sites near the Al impurity has been discovered and their spatial conf...
