摘要：

The adsorbate-substrate system Te-W(211) is studied in the temperature and coverage range 100<T<700 K and 1/4<1/2 by low-energy electron diffraction as a model of a domain-wall lattice. It is found that the structure at coverages intermediate between the limiting commensurate structures c(2×4)(=1/4) and p(2×1)(=1/2) can be described by a domain-wall lattice. The melting and disordering behavior of the system is extracted from a profile analysis of the diffraction features and discussed in terms of a simple theory of the domain-wall lattice in a uniaxial system with strong substrate potential and asymptotic power-law lateral interactions. © 1990 The American Physical Society.
