摘要：
A Monte Carlo study of the phase transitions on Ge(001) is carried out using the Ising model with axial next nearest neighbours interaction. It is shown that the transition between high and low temperature phases occurs via an intermediate modulated phase for definite relations of the interaction parameters. The period of the modulated phase depends on the temperature. The low temperature phase is found to be a c(4 x 2) structure. A phase diagram is obtained.
