Lattice-Gas Interface Structure: A Monte Carlo Simulation

Abstract

The (100), simple-cubic, lattice-gas interface structure has been simulated by Monte Carlo methods. For the interface width $L$ we find $L=(1.05\mathrm{}\pm 0.04){(1-\frac{T}{T_c})}^{-0.69\mathrm{}}$, in the range $T\gtrsim 0.5T_c$. This is larger than the bulk correlation length $\xi$ by a factor of ∼ 3.
