43. 3 has a relatively large band gap of 2.8 eV, contains 12-coordinated long A-O bonds (∼2.79 Å on average), and is considered to have weak bonds and interaction. The band structure calculated by VASP shows a larger band gap (1.68 eV) and small dispersion of the valence band, which should lead to a large effective mass and small hole conductivity.
