Notes:
The defect structure of undoped ZnO and (Zn1-x,Mgx)O solid-solution films were deposited onYSZ substrate with pulsed laser deposition (PLD) to investigate defect equilibria in those films. Inparticular, the effects of thermal treatment on the structures and prosperities of (Zn1-x,Mgx)O[removed info]solid-solution films were examined. The films with high MgO concentration (x〉0.12) decomposedto the wurtzite-type and rock-salt-type phase after thermal treatment, indicating that the solubilitylimit of Mg was about x=0.12 and the wurtzite-type (Zn,Mg)O films with x〉0.12 were indicated tobe non-equilibrium ones. The subsequent analyses of oxygen diffusivity in those films revealed thatthe films under non-equilibrium state, i.e., wurtzite-type (Zn1-x,Mgx)O with x〉0.12, containedsignificantly high concentration of anion defects
