✦ Synopsis
We have investigated a quasi-one-dimensional structure of Si(1 1 1)-8 Â 2-In surface using reflection high-energy positron diffraction (RHEPD) and scanning tunneling microscopy (STM). From the RHEPD rocking curve analyses, we confirmed the formation of the In hexagon structure proposed by Gonza ´lez et al. [C. Gonza ´lez, F. Flores, J. Ortega, Phys. Rev. Lett. 96 (2006) 136101]. Furthermore, we found that the emptystate STM image at 44 K is consistent with that calculated with the optimum hexagon structure by the RHEPD analyses.
