Scanning tunnelling microscopic data were obtained for the reconstructed surfaces, Si(110) 16 x 2 and Si(110) 5 x 1. Models for both surface reconstructions were proposed which were based upon a single building-block; a face-centered stretched hexagon of adatoms. This building-block could account for 23 major features of the 16 x 2 and 5 x 1 reconstructions, and explained why these reconstructions occurred.
