摘要：

We study the phase separation of the O/W(110)-p(2×1)+p(2×2) system with LEED as it is quenched from an infinite-temperature initial state to within its coexistence region. Novel features of this system are the fourfold degeneracy of the ordered phases and their finite densities. The measured growth exponent is consistent with the Lifshitz-Slyozov prediction x=1/3. Diffusion activation energies measured with two independent methods are consistent with each other and lead to E0.58 eV. © 1990 The American Physical Society.
