Image of FIG. 1.
FIG. 1.

AFM topographic images of 30 nm thick LSMO films grown in the same conditions on (a) STO(001) and (b) STO(110). They are presented with the corresponding profiles (bottom panel) and RHEED patterns (insets). Other inset in (b) is an AFM topographic image of a STO(110) substrate surface shown after thermal treatment (, 2 h in air).

Image of FIG. 2.
FIG. 2.

RHEED and AFM characterizations of LSMO(110) films grown at different D/F ratios [which are compared with the corresponding to Fig. 1(b)] by changing f and . (a) , 0.5 Hz, (b) , 2 Hz, (c) , 1 Hz. In the left panel are the RHEED intensity evolutions in the early stage of growth up to , and the RHEED patterns taken along the [1–10] direction after the growth of the thick films. AFM topographic images of the films are presented in the right panel. The insets in the right panel in (a) is a closer 3D view of the corresponding AFM image; and in (b) is the RHEED intensity evolution showing oscillations (emphasized by the dashed arrows pointing at the maxima) during the last stages of growth, and recovery at the end.

Image of FIG. 3.
FIG. 3.

(a) rms surface roughness plotted against f of the films grown at and . (b) Summarizing sketch, mapping the growth mode, and the resulting morphology as a function of the deposition temperature and the laser repetition rate.
