microscopy (STM) to study the rutile TiO2 (011) surface. A series of (2 n× 1) reconstructions
were observed, including two types of (4× 1) reconstruction. High-resolution NC-AFM and
STM images indicate that the (4× 1)-α phase has the same structural elements as the more
widely reported (2× 1) reconstruction. An array of analogous higher-order (2 n× 1)
reconstructions were also observed where n= 3–5. On the other hand, the (4× 1)-β …
