Pulsed laser ablation epitaxial Strancky-Krastanow growth of self-organized
complex oxide Ce:BaTiO3 quantum dots on MgO(100) substrates is demonstrate
d. Atomic force microscopy and Xray diffraction are used to observe the str
ucture and the growth process of the self-organized complex oxide quantum d
ots. The average dimension, height, and the density of self-organized compl
ex oxide Ce:BaTiO3 quantum dots are given. The nonlinear refractive indexes
of the wetting layer and the self-organized ordered quantum dots are deter
mined by the single beam Z-scan method. The mechanisms of the nonlinear eff
ect enhancement for these low-dimensional structure are discussed.
