摘要：

We have studied a Si(110) "7 x 2" (((1) over bar, 6) x (2, 2))-Sn surface by means of scanning tunneling microscopy (STM). High-resolution STM images have shown that Sn trimers and Si pentagons are arranged regularly in the "7 x 2" surface. The Si pentagons, which are the elemental structures of clean Si(110) "16 x 2", are rearranged in the presence of Sn trimers. The Si pentagons are pronouncedly imaged in the empty states, due to the charge transfer from Si pentagons to Sn trimers.
