Figure 1

A low magnification BF-TEM image of (PBMO)0.5:(CeO2)0.5 film (a) and (PBMO)0.8:(CeO2)0.2 film (b) on LSAT substrate, recorded along the [100] LSAT zone axis. The corresponding SAED pattern of the nanocomposite film is inserted. A horizontal white arrow in (a,b) indicates the film-substrate interface. CeO2 nanopillars embedded in PBMO matrix with different dimensions are indicated by a vertical yellow arrow and a vertical red arrow, respectively. In the inserted SAED pattern, the diffraction spots from PBMO matrix are indicated by a green open square. Two sets of diffraction spots from CeO2 nanopillars are denoted by a vertical yellow arrow and a horizontal red arrow, respectively. (c) A high-resolution HAADF-STEM image of (PBMO)0.8:(CeO2)0.2 film showing two types of ORs between CeO2 and PBMO, viewed along the [100] PBMO zone axis. The interfaces is indicated by yellow dashed lines and red dashed lines.
