Tris(cyclopentadienyl)yttrium, and for comparison Y(MeCp)3, (both with H2O as O source) was applied as precursor for the ALD growth of cubic Y2O3 thin films on Si substrates at temperature as low as 175°C. The crystallinity, morphology, and chemical composition of the obtained Y2O3 layers was studied by XRD, AFM, and TOF-ERDA, respectively. The smoothest yttria layers were obtained at ≤250 °C with both precursors. See links below
