Abstract
It is proposed that cleavage of Si to form Si(111) (2×1) occurs by the scission of three bonds between the closely spaced double layers, rather than by the severing of the single bond that connects the double layers. It is shown that three‐bond scission occurs in the behavior of dislocations in Si. Models of the surface structure based on this cleavage process are presented and discussed in light of the current understanding of this surface.
