摘要
We have investigated a quasi-one-dimensional structure of In/Si(111) surface using reflection high-energy positron diffraction (RHEPD), which is sensitive to the topmost surface structure under the total reflection condition. From the rocking curves, we found that In atoms are located at two different vertical positions, i.e., 0.99 angstrom and 0.55 angstrom from the Si zigzag chain in both 4 x 1 (210 K) and 8 x 2 (60 K) phases.
