Abstract

Structural and electrical properties of $Eu_2O_3$ films grown on Si(100) in 500–600 °C temperature range by low pressure metalorganic chemical vapor deposition are reported. As-grown films also possess the impurity $Eu_{1-x}O$ phase, which has been removed upon annealing in $O_2$ ambient. Film’s morphology comprises uniform spherical mounds 40–60 nm. Electrical properties of the films, as examined by capacitance-voltage measurements, exhibit fixed oxide charges in the range of $-1.5\times10^{11}$ to $-6.0\times10^{10} cm^{-2}$ and dielectric constant in the range of 8–23. Annealing has resulted in drastic improvement of their electrical properties. Effect of oxygen nonstoichiometry on the film’s property is briefly discussed.
