    • If Refs.[14] and [15] are right in that for all easily formable defects the ionization energy is very small, we might have to refer to extrinsic defects such as substitutional oxygen impurities to efficiently capture the holes (close to the valence band). However, already slightly higher energies that are within the accuracy of such modeling can lead to substantial trapping, if the number of trap centers is very high, as it is the case for ionic disorder. So also intrinsic defects cannot be excluded as trap centers.
