Abstract
In terms of the antiferromagnetic XY-model on a triangular lattice in two dimensions, the mechanisms of (111) surface reconstructions of homopolar semiconductors are reconsidered. The validity of the proposed model is examined by comparing it with several experimental results, with which satisfactory agreement is obtained. In particular, the present model leads to the stability of the 5*5 and the 7*7 structures as well as a high probability of the nucleation of the N*N dimer adatom stacking-fault reconstruction from an upper step edge.
