Dopant-induced bandgap shift in Al-doped ZnO thin films prepared by spray pyrolysis
A series of 1 at. Al-doped ZnO (AZO) films were deposited onto glass substrates by a spray pyrolysis technique. We find that the observed blue shift in the optical bandgap of 1 AZO films is dominated by the Burstein Moss effect. The Fermi level for an 807 nm thick AZO film rose by some 0.16 eV with...
