摘要：

The clean Mo(100) surface reconstructs at low temperature forming a commensurate c(7 square-root 2 x square-root 2)R45-degrees displacement wave. LEED studies over the range 10 to 300 K reveal a change in the harmonic content of this wave at intermediate temperatures corresponding to a sharpening of antiphase domain walls as T is lowered. Simultaneously, a selection of one of two possible domain orientations occurs if steps are present. The process shows no hysteresis and permits the equilibrium distribution to be observed.
