- 論文の詳細を見る
The structure change of SrTiO_3(111) polar surfaces was studied as a function of atmosphere, by atomic force microscopy, Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS). The SrTiO_3 (111) surfaces annealed in oxygen gas had a trench structure, while the surfaces annealed in argon gas formed large triangular terraces. The surfaces annealed in air, i.e., in intermediate oxygen partial pressure, consisted of complicated self-similar triangles with different sizes, forming a fractal shape called Sierpinski's gasket. The XPS analyses indicated that surface oxygen states were different depending on the annealing atmosphere.
