Effects of thickness on the cation segregation in epitaxial (001) and (110) La2/3Ca1/3MnO3 thin films

# metadata.dc.description.abstract[].value
Electron-energy-loss spectroscopy is used to map composition and electronic states in epitaxial La2/3Ca1/3MnO3 LCMO  films of various thicknesses grown on SrTiO3 001  and 110  substrates. For relatively thick films 20 nm , epitaxial tensile strain in 001  films promotes a compositional La/Ca gradient across the film thickness, being the interface La rich, while the relaxed 110  films are chemically homogeneous. In contrast, much thinner 001  and 110  LCMO films display a different La/Ca distribution, being La rich at the free surface. The observed distinct thickness-dependent composition gradient behavior reflects a balance between strain-induced elastic energy minimization and kinetic effects during growth.
