可见激光 (442nm) 照射在金红石 TiO2(110)-(1 × 1) 表面上形成原子级结构。创建的明亮结构，形状像领结，具有连接两个相邻 Ti [001] 行的外观。该结构的正面和背面也显示出黑暗区域。该结构被解释为 (1 × 1) 表面上的氧缺陷，以及由于氧原子从其原始位置移位而导致结构周围的黑点之一。该结构通常表现为沿[110]方向排列的一对，可以将其视为局部（2×3）结构。
Visible laser light (442nm) irradiation created an atomic-scale structure on a rutile TiO2(110)-(1 × 1) surface. The created bright structure, shaped like a bow tie, had an appearance of connecting two neighboring Ti [001] rows. The structure also showed dark areas in its front and in its back. The structure was interpreted as an oxygen deficiency on the (1 × 1) surface, and one of the dark spots around the structure as the oxygen atom displaced from its original position. The structure often appeared as a pair aligned along [110] direction, which could be viewed as a local (2 × 3) structure.
