Abstract

Electrically conductive LaNiO3-δ thin film with perovskite-type structure were deposited on Si(100)/n substrates by rf magnetron sputtering at substrate temperature 200°C , 300°C, 450°C, 600°C with a series of 0%, 20%, 40%, 60% oxygen partial pressure respectively. The La2NiO4 and NiO peak of XRD are not observed. The RT resistivity of LNO films decreases with the decreasing substrate temperature at a fixed oxygen partial pressure and with increasing oxygen partial pressure at a fixed substrate temperature.
