The structure of yttrium stabilized ZrO2 crystals with intermediate seam la
yers of CeO2 and SrTiO3 has been studied by transmission electron microscop
y (TEM). Such crystals were fabricated by the solid phase intergrowth metho
d (SPI). The interfaces between ZrO2 and CeO2 layers were blurred compared
to the sharp interfaces between CeO2 and SrTiO3 layers. The CeO2 layers wer
e single crystalline with a high density of defects. The SrTiO3 layers cons
isted of columnar grains. Epitaxial relationships have been established. (C
