On the basis of scanning tunnelling microscopic measurements, a model was proposed for the so-called 16 x 2 reconstruction into which the (110) surface organized itself. The model reproduced features such as alternating light and dark stripes, with atom-high (0.192nm) steps between them. The up-stripes were oriented along either the [1¯1¯2] direction or the [¯11¯2] direction. These formed a chevron at their points of intersection, with a reflection symmetry in the vertical mirror plane.
