Abstract:
A scanning tunneling microscope has been used to study the Si(111)-3×1-Ag surface. The 3×1-Ag surface has been observed to consist of a bright row and small protrusions; the bright row points in the 〈 1̄10 〉 direction and the protrusions point in the 〈 123̄ 〉 and 〈 213̄ 〉 directions. The width of 3×1- A g domains, nucleated on the Si-7×7 terraces, has been found to be (21 n -2) a , where n is an integer ( n =1, 2,···) and a is the lattice constant of Si ( a =3.84 Å). Detailed investigation on domain boundaries reveals that both sides of the 3×1-Ag domain face the unfaulted halves of the 7×7 structure. Moreover, two types of domain boundaries have been observed: one which runs across the corner holes, and another is that runs apart from the corner holes, leaving a narrow 7×7 terrace of one adatom width. Possible structural models for the 3×1-Ag surface are proposed based on the present STM results.
