Abstract
Laser molecular beam epitaxy (laser MBE) technique was utilized to gro w the barium titanate (BaTiO3, BTO) thin films on SrTiO3(100) substrat es. The surface morphology of the BaTiO3 thin films was studied by ato mic force microscopy (AFM). Two- and three-dimensional AFM images were obtained. The root mean square surface roughness, the height profile, the histogram and the bearing ratio of the height distributions for t he BaTiO3 thin films were analyzed in detail. The results indicate tha t the laser MBE thin films exhibit an atomically smooth surface.
