Phys. Rev. B 53, 1002–1005 (1996)Vicinal Si(100) surfaces under external strainReceived 11 September 1995; published in the issue dated 15 January 1996 The phase diagram of vicinal Si(100) surfaces is calculated as a function of misorientation angle, temperature, and applied external strain. It is shown that a change of the applied external strain can lead to a phase transition between the single-layer step surface phase and the double-layer step surface phase. The effect of temperature is shown to be negligible up to 300 K. The order parameter of the surface phase transition is also calculated to make contact with experimental measurements. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
