Micrometer-wide, single-domain of 16 x 2 reconstruction, the array of straight mono-atomic steps, was fabricated on Si(110) surface by means of controlled electromigration of surface atoms. The electromigration effect during direct-current heating was found to line-up the reconstruction rows when the current direction matches to the direction of the rows. This provides not only a well-controlled surface preparation method for Si(110), but also a new template for low-dimensional nanostructures.
