摘要

将经过氢氟酸处理和退火的TiO2(110)单晶衬底浸入苯胺的乙醇溶液中，观察到在不含苯胺的TiO2(110)表面呈[001]方向的均匀阶梯结构。由于这一发现被认为是对TiO2(110)表面台阶方向的控制，因此对形成的表面进行了详细的讨论，并提出了台阶线形成过程的模型。将TiO2(110)单晶衬底浸入含有苯胺的乙醇溶液后，虽然不存在苯胺，但TiO2(110)表面却形成了沿[001]方向的均匀阶梯结构。提出了一种合理的阶梯线形成过程模型。本研究结果导致了控制TiO2(110)表面台阶方向的新方法。

Etching of TiO₂(110) Single-Crystal Surface with Aniline for Step Direction Control

After subjecting a hydrofluoric acid treated and annealed TiO2(110) single-crystal substrate to immersion in an ethanol solution of aniline, a uniform step structure in the [001] direction was observed on the TiO2(110) surface without aniline. Since this finding is considered to control of the step direction on the TiO2(110) surface, the formed surface was discussed in detail and a model of the step line formation process was proposed. After immersing of TiO2(110) single-crystal substrate in an ethanol solution containing aniline, a uniform step structure in the [001] direction formed on the TiO2(110) surface although aniline was not existed. A reasonable model of the step line formation process was proposed. The present results lead to the novel method to control of the step direction on the TiO2(110) surface.
