Bistability of Hydrogen in ZnO: Origin of Doping Limit and Persistent Photoconductivity
Substitutional hydrogen at oxygen site (H(O)) is well-known to be a robust source of n-type conductivity in ZnO, but a puzzling aspect is that the doping limit by hydrogen is only about 10(18) cm(−3), even if solubility limit is much higher. Another puzzling aspect of ZnO is persistent photoconducti...
