Abstract
We report on the effect of carbon doping on electrical properties of epitaxial Gd2O3 grown on Si substrates. The incorporation of small amounts of carbon (0.2-0.5 vol. ) into epitaxial Gd2O 3 has been found to be very useful in improving the electrical properties especially by reducing the leakage current behavior. The doping has a negligible impact on the structural quality of the oxide layer. We show that the very often found adverse effect of oxygen vacancy induced defects in oxides grown at higher temperature can be eliminated by moderate amount of carbon doping during growth.
