Phys. Rev. Lett. 61, 2469–2471 (1988)Si(100) Surface under an Externally Applied StressReceived 11 July 1988; published in the issue dated 21 November 1988 Loading a cantilevered bar allows studying the effect of a uniform, externally applied, and continuously variable strain field on the properties of surfaces. Straining a nominally flat Si(100) surface produces unequal populations of the 2 × 1 and 1 × 2 domains. The domain compressed along the dimer bond is favored. The effect depends on the strain and not the strain gradient. The effect saturates at a strain of 0.1% when 90% of the surface is in the favorable domain. The kinetics of developing and annealing away the asymmetry are identical and thermally activated. © 1988 The American Physical Society URL:
