摘要：

Metallic oxide films of SrRuO3 deposited on (001) SrTiO3 by pulsed laser deposition have been investigated by transmission electron microscopy (TEM) techniques. These films have a single crystalline structure with an extremely smooth surface. A TEM study of cross-sectional samples shows that the film grew epitaxially on the (001) surface of the SrTiO3 substrate. The films grew along the [110] directions with an in-plane orientation relationship of either SrRuO3[<(1)over bar 10>]//SrTiO3 [100] and SrRuO3[001]//SrTiO3[010], or SrRuO3[1(1) over bar0$]/SrTiO3[010] and SrRuO3[001]//SrTiO3 [100]. Domains with a rotation of 90 degrees around SrRuO3[110] were observed in the dark-field image of plan-view samples. (C) 1998 American Institute of Physics.
