The instabilities of a phase boundary are investigated in a system corresponding to the two-dimensional attractive lattice-gas model driven by a uniform external field. On the analogy of Mullins-Sekerka instability the planar interface becomes unstable due to the enhanced material transport along the interface. This phenomenon explains why the particles are condensed on strips parallel to the driving field at low temperatures.
