“…due to the sample size and the contact spot size, which estimated to be about 5%. The measured electrical parameters of pure reference CdO film in the present work are in agreement with those data published for CdO films prepared by different techniques [1,26,27,[30][31][32]. However, the measured resistivity of CdO, in the present work, is larger than those values mentioned in some other references~10 − 3 -10 − 4 Ω cm due to the different method and procedure of preparation.…”
