Epitaxial Growth of Bi2Sr2CuO6 Thin Films on Single Crystal Surfaces.

ABSTRACTEpitaxial growth of Bi2Sr2CuO6 thin films on a SrTiO3, a misoriented SrTiO3 and a Bi2Sr2CaCu2O8 single crystal have been performed using computer-controlled laser molecular beam epitaxy. On the SrTiO3 substrate, the 2201 films consist of two types of domains whose b-axes are perpendicular to each other. In contrast, the 2201 film on the 2212 single crystal has a complete single type of domains. Layer-by-layer growth with a half unit cell thickness of 2201 films is observed.
