Before revision:  Moreover, the interface width exhibits logarithmic growth with the time, instead of saturation , in the long-time limit. Furthermore, we find that evaporation dominates the growth process when the coefficient of the nonlinear term in the KPZ equation is small, and that  average radius of  interface decreases with time and reaches a minimum but not zero value.
