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
