Monte Carlo simulations are performed on a square lattice-gas model with a repulsive interaction under the influence of a uniform electric field. Pair-correlation and particle-distribution studies show those polydomain states with strips parallel to the driving field to be stable in the low-temperature region. These results agree with the disappearance of the λ singularity in the specific heat. The formation of the anisotropic polydomain state may be explained by induced interfacial material transport, leading to the instability of planar interfaces.
