Heteroepitaxial Growth of Yttria-Stabilized Zirconia (YSZ) on Silicon

Abstract
Yttria-stabilized zirconia (YSZ) films have been grown on Si(100) substrates heated at 800°C by vacuum evaporation. X-ray diffraction and reflection high-energy electron diffraction observations reveal the heteroepitaxial growth of cubic YSZ (200) films on Si(100) substrates. The reflection high-energy electron diffraction of the films show that the and directions in the plane of cubic YSZ nearly coincide with the and directions of the Si substrate, respectively. Accordingly, (200)-oriented cubic YSZ could be exactly (<1%) lattice-matched to (100)-oriented Si substrates.
