abstract = {Pyrochlore-type (Ca,Ti)2(Nb,Ti)2O7 thin films have been
grown on single-crystalline LaAlO3 and yttria-stabilized
zirconia substrates by a magnetron sputtering system.
Atomic-scale interface structure and growth mode of the
(Ca,Ti)2(Nb,Ti)2O7 films on the substrates with different
crystal structures have been investigated by advanced
electron microscopy techniques. In both heterosystems, the
film/substrate orientation relationship of
[100](001)film//[100](001)substrate has been determined. In
the heterosystem of (Ca,Ti)2(Nb,Ti)2O7/yttria-stabilized
zirconia, the films directly grow on the substrates. In
contrast, in the (Ca,Ti)2(Nb,Ti)2O7/LaAlO3 heterosystem, a
perovskite-type Ca1-□(Ti,Nb)O3 interlayer with a few unit
cells in thickness forms at the interface and interfacial
reconstruction occurs at the
(Ca,Ti)2(Nb,Ti)2O7/Ca1-□(Ti,Nb)O3 interface. Our findings
indicate that the formation of the interlayer and the
(Ca,Ti)2(Nb,Ti)2O7/Ca1-□(Ti,Nb)O3 interface reconstruction
can accommodate the film/substrate dissimilarities in the
crystal structures and facilitate the growth of
single-crystalline pyrochlore-type films on the
perovskite-type substrates.},
