Research Abstract

Atomic-scale studies on initial growth process of artificial perovskite titanate exhibiting a broad range of physical properties were carried out. Using a genuinely atomically-ordered single-crystal substrate, growth chemistry of thin-film oxides was elucidated by means of scanning tunneling microscopy. These results can provide significant insight into the improvement of device performances, leading to creation of higher-quality materials.
