Transparent high-surface-work-function Al-doped CdO electrodes obtained by rf magnetron sputtering with oxygen flow

► AlCdO films were deposited by rf magnetron sputtering with and without oxygen flow. ► For AlCdO films deposited with oxygen flow, we measure the high work function. ► For AlCdO films deposited without oxygen flow, we measure the low work function. ► It is shown the peroxidic AlCdO surface with a high work function.
