摘　　要：The reconstruction of the dimerized overlayer system with vacancies is studied via a diatomic chain Frenkel Kontorova model.We present the details of the exactly solvable model and the analytical solution of the atomic displacements in the ground state.Our calculations explain the 2×N reconstruction observed in Ge/Si(100)and Ga/Si(112).
