Abstract
The reconstruction of the dimerized overlayer system with vacancies is stud ied via a diatomic chain Frenkel-Kontorova model. We present the details of the exactly solvable model and the analytical solution of the atomic displ acements in the ground state. Our calculations explain the 2 x N reconstruc tion observed in Ge/Si(100) and Ga/Si(112).
